1. Field of the Invention
The invention relates to a catadioptric projection objective for imaging a pattern arranged in an object surface onto an image surface.
2. Description of the Related Art
Projection objectives of that type are employed on projection exposure systems, in particular wafer scanners or wafer steppers, used for fabricating semiconductor devices and other types of microdevices and serve to project patterns on photomasks or reticles, hereinafter referred to generically as “masks” or “reticles,” onto an object having a photosensitive coating with ultrahigh resolution on a reduced scale.
In order create even finer structures, it is sought to both increase the image-end numerical aperture (NA) of the projection objective to be involved and employ shorter wavelengths, preferably ultraviolet light with wavelengths less than about 260 nm.
However, there are very few materials, in particular, synthetic quartz glass and crystalline fluorides, that are sufficiently transparent in that wavelength region available for fabricating the optical elements required. Since the Abbé numbers of those materials that are available lie rather close to one another, it is difficult to provide purely refractive systems that are sufficiently well color-corrected (corrected for chromatic aberrations).
In lithography, a flat (planar) image is essential to expose planar substrates, such as semiconductor wafers. However, generally the image surface of an optical system is curved, and the degree of curvature is determined by the Petzval sum. The correction of the Petzval sum is becoming more important in view of the increasing demands to project large object fields on planar surfaces with increased resolution.
One approach for obtaining a flat image surface and good color-correction is the use of catadioptric systems, which combine both refracting elements, such as lenses, and reflecting elements, such as mirror, preferably including at least one concave mirror. While the contributions of positive-powered and negative-powered lenses in an optical system to overall power, surface curvature and chromatic aberrations are opposite to each other, a concave mirror has positive power like a positive-powered lens, but the opposite effect on surface curvature without contributing to chromatic aberrations.
Further, the high prices of the materials involved and limited availability of crystalline calcium fluoride in sizes large enough for fabricating large lenses represent problems. Measures that will allow reducing the number and sizes of lenses and simultaneously contribute to maintaining, or even improving, imaging fidelity are thus desired.
Catadioptric projection objectives having at least two concave mirrors have been proposed to provide systems with good color correction and moderate lens mass requirements. The U.S. Pat. No. 6,600,608 B1 discloses a catadioptric projection objective having a first, purely refractive objective part for imaging a pattern arranged in the object plane of the projection objective into a first intermediate image, a second objective part for imaging the first intermediate image into a second intermediate image and a third objective part for imaging the second intermediate image directly, that is without a further intermediate image, onto the image plane. The second objective part is a catadioptric objective part having a first concave mirror with a central bore and a second concave mirror with a central bore, the concave mirrors having the mirror faces facing each other and defining an intermirror space or catadioptric cavity in between. The first intermediate image is formed within the central bore of the concave mirror next to the object plane, whereas the second intermediate image is formed within the central bore of the concave mirror next to the object plane. The objective has axial symmetry and provides good color correction axially and laterally. However, since the reflecting surfaces of the concave mirrors are interrupted at the bores, the pupil of the system is obscured.
The Patent EP 1 069 448 B1 discloses another catadioptric projection objective having two concave mirrors facing each other. The concave mirrors are part of a first catadioptric objective part imaging the object onto an intermediate image positioned adjacent to a concave mirror. This is the only intermediate image, which is imaged to the image plane by a second, purely refractive objective part. The object as well as the image of the catadioptric imaging system are positioned outside the intermirror space defined by the mirrors facing each other. Similar systems having two concave mirrors, a common straight optical axis and one intermediate image formed by a catadioptric imaging system and positioned besides one of the concave mirrors are disclosed in Japanese patent application JP 2002208551 A and US patent application US 2002/00241 A1.
European patent application EP 1 336 887 (corresponding to US 2004/0130806 A1) discloses catadioptric projection objectives having one common straight optical axis and, in that sequence, a first catadioptric objective part for creating a first intermediate image, a second catadioptric objective part for creating a second intermediate image from the first intermediate image, and a refractive third objective part forming the image from the second intermediate image. Each catadioptric system has two concave mirrors facing each other. The intermediate images lie outside the intermirror spaces defined by the concave mirrors. Concave mirrors are positioned optically near to pupil surfaces closer to pupil surfaces than to the intermediate images of the projection objectives.
International Patent application WO 2004/107011 A1 discloses catadioptric projection objectives having one common straight optical axis and two or more intermediate images and suitable for immersion lithography with numerical apertures up to NA=1.2. At least one concave mirror is positioned optically near to a pupil surface closer to that pupil surface than to an intermediate images of the projection objective.
In the article “Nikon Projection Lens Update” by T. Matsuyama, T. Ishiyama and Y. Ohmura, presented by B. W. Smith in: Optical Microlithography XVII, Proc. of SPIE 5377.65 (2004) a design example of a catadioptric projection lens is shown, which is a combination of a conventional dioptric DUV system and a 6-mirror EUV catoptric system inserted between lens groups of the DUV system. A first intermediate image is formed behind the third mirror of the catoptric (purely reflective) group upstream of a convex mirror. The second intermediate image is formed by a purely reflective (catoptric) second objective part. The third objective part is purely refractive featuring negative refractive power at a waist of minimum beam diameter within the third objective part for Petzval sum correction.
Japanese patent application JP 2003114387 A and international patent application WO 01/55767 A disclose catadioptric projection objectives having one common straight optical axis, a first catadioptric objective part for forming an intermediate image and a second catadioptric objective part for imaging the intermediate image onto the image plane of this system. Concave and convex mirrors are used in combination.
The article “Camera view finder using tilted concave mirror erecting elements” by D. DeJager, SPIE. Vol. 237 (1980) p. 292-298 discloses camera view finders comprising two concave mirrors as elements of a 1:1 telescopic erecting relay system. The system is designed to image an object at infinity into a real image, which is erect and can be viewed through an eyepiece. Separate optical axes of refractive system parts upstream and downstream of the catoptric relay system are parallel offset to each other. In order to build a system having concave mirrors facing each other mirrors must be tilted. The authors conclude that physically realizable systems of this type have poor image quality.
International patent applications WO 92/05462 and WO 94/06047 and the article “Innovative Wide-Field Binocular Design” in OSA/SPIE Proceedings (1994) pages 389ff disclose catadioptric optical systems especially for binoculars and other viewing instruments designed as inline system having a single, unfolded optical axis. Some embodiments have a first concave mirror having an object side mirror surface arranged on one side of the optical axis and a second concave mirror having a mirror surface facing the first mirror and arranged on the opposite side of the optical axis such that the surface curvatures of the concave mirrors define and intermirror space. A front refractive group forms a first intermediate image near the first mirror and a second intermediate image is formed outside of the space formed by the two facing mirrors. A narrow field being larger in a horizontal direction than in a vertical direction is arranged offset to the optical axis. The object side refractive group has a collimated input and the image side refractive group has a collimated output and entrance and exit pupils far from telecentric are formed. The pupil shape is semi-circular unlike pupil surfaces in lithographic projection lenses, which have to be circular and centered on the optical axis.
The PCT application WO 01/044682 A1 discloses catadioptric UV imaging systems for wafer inspection having one concave mirror designed as Mangin mirror.
Catadioptric projection objectives consisting of a catadioptric imaging subsystem having one single concave mirror and arranged between an entry side and an exit side refractive imaging subsystem (so-calles R-C-R systems) are disclosed, for example, in U.S. application with Ser. No. 60/573,533 filed on May 17, 2004 by the applicant. Other examples of R-C-R-systems are shown in US 2003/0011755, WO 03/036361 or US 2003/0197946.
US patent application with title “Catadioptric Projection Objective” filed by the applicant on Jan. 14, 2005 (based on U.S. provisional applications 60/536,248 filed on Jan. 14, 2004; U.S., 60/587,504 filed Jul. 14, 2004; 60/617,674 filed Oct. 13, 2004; 60/591,775 filed Jul. 27, 2004; and 60/612,823 filed Sep. 24, 2004) discloses catadioptric projection objectives having very high NA and suitable for immersion lithography at NA>1 with maximum values NA=1.2. The projection objectives comprise: a first objective part for imaging the pattern provided in the object plane into a first intermediate image, a second objective part for imaging the first intermediate imaging into a second intermediate image, and a third objective part for imaging the second intermediate imaging directly onto the image plane. The second objective part includes a first concave mirror having a first continuous mirror surface and a second concave mirror having a second continuous mirror surface, the concave mirror faces facing each other and defining an intermirror space. All concave mirrors are positioned optically remote from pupil surfaces. The system has potential for very high numerical apertures at moderate lens mass consumption. The full disclosure of this document and the priority documents thereof is incorporated into the present application by reference.
It is one object of the invention to provide a catadioptric projection objective suitable for use in the vacuum ultraviolet (VUV) range having potential for very high image side numerical aperture which may be extended to values allowing immersion lithography at numerical apertures NA>1. It is another object to provide catadioptric projection objectives that can be build with relatively small amounts of optical material. It is yet another object to provide compact high-aperture catadioptric projection objectives having moderate size.
As a solution to these and other objects the invention, according to one formulation, provides a catadioptric projection objective for imaging a pattern provided in an object surface of the projection objective onto an image surface of the projection objective comprising:
Generally, the dimensions of projection objectives tend to increase dramatically as the image side numerical aperture NA is increased. Empirically it has been found that the maximum lens diameter Dmax tends to increase stronger than linear with increase of NA according to Dmax˜NAk, where k>1. A value k=2 is an approximation used for the purpose of this application. Further, it has been found that the maximum lens diameter Dmax increases in proportion to the image field size (represented by the image field height Y′). A linear dependency is assumed for the purpose of the application. Based on these considerations a first compactness parameter COMP1 is defined as:
COMP1=Dmax/(Y′·NA2).
It is evident that, for given values of image field height and numerical aperture, the first compaction parameter COMP1 should be as small as possible if a compact design is desired.
Considering the overall material consumption necessary for providing a projection objective, the absolute number of lenses, NL is also relevant. Typically, systems with a smaller number of lenses are preferred to systems with larger numbers of lenses. Therefore, a second compactness parameter COMP2 is defined as follows:
COMP2=COMP1·NL.
Again, small values for COMP2 are indicative of compact optical systems.
Further, projection objectives according to the invention have at least three objective parts for imaging an entry side field plane into an optically conjugate exit side field plane, where the imaging objective parts are concatenated at intermediate images. Typically, the number of lenses and the overall material necessary to build a projection objective will increase the higher the number NOP of imaging objective parts of the optical system is. It is desirable to keep the average number of lenses per objective part, NL/NOP, as small as possible. Therefore, a third compactness parameter COMP3 is defined as follows:
COMP3=COMP1·NL/NOP.
Again, projection objectives with low optical material consumption will be characterized by small values of COMP3.
A value COMP1<10 indicates a very compact design. Even values of COMP1<9.6 are obtained in some embodiments. In some embodiments the low compactness is obtained although the numerical aperture is larger than 1.2 (i.e. NA>1.2). Embodiments with NA=1.3 or NA=1.35 are possible and allow ultra-high resolution immersion lithography.
In some embodiments, low values for the second compactness parameter can be obtained. In some embodiments COMP2<260 and/or COMP2<240 is obtained. Embodiments with COMP2<220 are possible.
Alternatively, or in addition, low values for the third compactness parameter COMP3 are possible. In some embodiments COMP3<80, and lower values of COMP3<70 are also possible.
In preferred embodiments, a first concave mirror having a first continuous mirror surface and at least one second concave mirror having a second continuous mirror surface are arranged in the second objective part; pupil surfaces are formed between the object plane and the first intermediate image, between the first and the second intermediate image and between the second intermediate image and the image plane; and all concave mirrors are arranged optically remote from a pupil surface.
In these embodiments a circular pupil centered around the optical axis is be provided in a centered optical system. Two or more concave mirrors in the system parts contributing to forming the second intermediate image are provided, where the used area of the concave mirrors deviates significantly from an axial symmetric illumination. In preferred embodiments exactly two concave mirrors are provided and are sufficient for obtaining excellent imaging quality and very high numerical aperture. Systems having one common unfolded (straight) optical axis can be provided which facilitate manufacturing, adjustment and integration into photolithographic exposure systems. No planar folding mirrors are necessary. However, one or more planar folding mirrors could be utilized to obtain more compact designs.
All concave mirrors are arranged “optically remote” from pupil surfaces which means that they are arranged outside an optical vicinity of a pupil surface. They may be arranged optically nearer to field surfaces than to pupil surfaces. Preferred positions optically remote from a pupil surface (i.e. outside an optical vicinity of a pupil surface) may be characterized by the ray height ratio H=hC/hM>1, where hC is the height of a chief ray and hM is the height of a marginal ray of the imaging process. The marginal ray height hM is the height of a marginal ray running from an inner field point (closest to the optical axis) to the edge of an aperture stop, whereas the chief ray height hC is the height of a chief ray running from an outermost field point (farthest away from the optical axis) parallel to or at small angle with respect to the optical axis and intersecting the optical axis at a pupil surface position where an aperture stop may be positioned. With other words: all concave mirrors are in positions where the chief ray height exceeds the marginal ray height.
A position “optically remote” from a pupil surface is a position where the cross sectional shape of the light beam deviates significantly from the circular shape found in a pupil surface or in an immediate vicinity thereto. The term “light beam” as used here describes the bundle of all rays running from the object surface to the image surface. Mirror positions optically remote from a pupil surface may be defined as positions where the beam diameters of the light beam in mutually perpendicular directions orthogonal to the propagation direction of the light beam deviate by more than 50% or 100% from each other. In other words, illuminated areas on the concave mirrors may have a shape having a form strongly deviating from a circle and similar to a high aspect ratio rectangle corresponding to a preferred field shape in lithographic projection objectives for wafer scanners. Therefore, small concave mirrors having a compact rectangular or near rectangular shape significantly smaller in one direction than in the other may be used. A high aperture light beam can therefore be guided through the system without vignetting at mirror edges.
Throughout the specification, the term “objective part” designates an imaging subsystem of the projection objective capable of imaging an object in an object surface of that subsystem into an image surface of the subsystem optically conjugated to the object surface of the subsystem. The object imaged by a subsystem (or objective part) may be the object in the object surface of the projection objective, or an intermediate image.
Wherever the terms “upstream” or “downstream” are used in this specification these terms refer to relative positions along the optical path of a light beam running from the object plane to the image plane of the projection objective. Therefore, a position upstream of the second intermediate image is a position optically between the object plane and the second intermediate image.
The term “intermediate image” generally refers to a “paraxial intermediate image” formed by a perfect optical system and located in a surface optically conjugated to the object surface. Therefore, wherever reference is made to a location or position of an intermediate image, the axial location of this surface optically conjugated to the object surface is meant.
According to another aspect of the invention, a catadioptric projection objective for imaging a pattern provided in an object surface of the projection objective onto an image surface of the projection objective comprises:
Although it would be desired from a manufacturing point of view to have lenses with spherical lens surfaces only, it appears that a certain number of aspheric lenses are required to obtain sufficient correction of image aberrations. It has been found that in designs where the third objective part has more aspheric lenses than the first objective part have potential for obtaining a good correction status without increasing the overall number, NAS, of aspheric lenses in the projection objective above a critical limit where the manufacturing of aspheric lenses becomes a critical issue due to the high number of aspheric lenses to be manufactured.
In some embodiments the first objective part has spherical lenses only such that N1AS=0. All-spherical refractive objective parts are particularly easy to manufacture. An all-spherical first objective part may be combined with a third objective part having one or more aspheric lenses, for example 1 or 2 or 3 or 4 or 5 lenses. Preferably the condition N3AS≦7 is fulfilled.
Preferably, the first objective part has no more than 4 aspheric lenses, i.e. N1AS≦4.
It has been found that the first objective part can be built in many cases with a small number of lenses, thereby optimizing lens material consumption and a compact size of the first objective part particularly in axial direction. In some embodiments, the first objective part includes no more than 5 lenses such that the number N1L of lenses in the first objective part fulfills the condition N1L≦5. Embodiments with N1L=4 are possible. It appears, however, that N1L=5 may be preferable in many cases.
In some embodiments, the first objective part has positive lenses only, whereby formation of the first intermediate image can be obtained with small maximum lens diameters in the first objective part. In other embodiments, at least one negative lens may be useful, particularly for improving correction within the first objective part. Exactly one negative lens is often preferred for that purpose. The negative lens may have a concave lens surface on the image side and may be placed between the pupil surface of the first objective part and the first intermediate image.
It is known that aspheric surfaces provided on optical elements, such as lenses, mirrors and/or essentially planar faces of plates, prisms or the like can be utilized to improve both the correction status and the overall size and material consumption of optical systems. In some embodiments, the projection objective includes at least one “double asphere” comprising a first aspheric surface and a second aspheric surface immediately adjacent to the first aspheric surface, thereby allowing a transmitted beam to pass two subsequent aspheric surfaces without passing an intermediate spheric or planar surface. Double aspheres have proven to be a very powerful correction means in some embodiments.
A double asphere may take the structure of a biaspherical lens having an aspheric entrance surface and an aspheric exit surface. In some preferred embodiments the double asphere is formed by facing adjacent aspheric surfaces of two subsequent lenses. Thereby, an “air space” bounded by aspheric surfaces on both the entry and exit side can be obtained. The “air space” can be filled with air of another gas having refractive index n≈1. Where aspheric surfaces of a double asphere are distributed on facing lens surfaces of subsequent lenses, the aspheric surfaces can be positioned very close together if desired. An optical distance, measured along the optical axis, between the first and second aspheric surface of the double asphere may therefore be smaller than the thickness (measured along the optical axis) of the thinner one of consecutive lenses forming the double asphere. A complex radial distribution of refractive power can thereby be obtained at a defined position in an axially narrow region along the optical axis.
In some embodiments, the third objective part includes at least one double asphere. Preferably, that double asphere is positioned optically between the second intermediate image and the pupil surface of the third objective part, thereby preferably influencing the ray angles in a region of generally diverging beams. A second double asphere may be provided in that objective part.
Alternatively, or in combination, the first objective part may include at least one double asphere. Where a double asphere is provided within the first objective part, it has been found beneficial when the double asphere in the first objective part is positioned optically close to or at a pupil surface of the first objective part.
As pointed out earlier, avoiding large numbers of aspheric surfaces on lenses may contribute to facilitating manufacturing of the projection objective. Under certain conditions, the correcting action of a single aspheric surface can be approximated by one or more spherical surfaces where large angles of incidence of rays occur on that surface. In some embodiments, the first objective part includes at least one lens having a lens surface where incidence angles of rays transiting that lens surface include incidence angles larger than 60°. Preferably, that surface may be optically close to the pupil surface The angle of incidence (incidence angle) in this case is defined as the angle enclosed by a ray and the surface normal of the lens surface at the point of impingement of that ray on the lens surface. High incidence angle surfaces of that kind may be employed to reduce the number of aspheres.
The previous and other properties can be seen not only in the claims but also in the description and the drawings, wherein individual characteristics may be used either alone or in sub-combinations as an embodiment of the invention and in other areas and may individually represent advantageous and patentable embodiments.
In the following description of preferred embodiments of the invention, the term “optical axis” shall refer to a straight line or sequence of straight-line segments passing through the centers of curvature of the optical elements involved. The optical axis is folded by folding mirrors (deflecting mirrors) or other reflective surfaces. In the case of those examples presented here, the object involved is either a mask (reticle) bearing the pattern of an integrated circuit or some other pattern, for example, a grating pattern. In the examples presented here, the image of the object is projected onto a wafer serving as a substrate that is coated with a layer of photoresist, although other types of substrate, such as components of liquid-crystal displays or substrates for optical gratings, are also feasible.
Where tables are provided to disclose the specification of a design shown in a figure, the table or tables are designated by the same numbers as the respective figures. Corresponding features in the figures are designated with like or identical reference identifications to facilitate understanding. Where lenses are designated, an identification L3-2 denotes the second lens in the third objective part (when viewed in the light propagation direction).
Each mirror surface of a concave mirror defines a “curvature surface” or “surface of curvature” which is a mathematical surface extending beyond the edges of the physical mirror surface and containing the mirror surface. The first and second concave mirrors are parts of rotationally symmetric curvature surfaces having a common axis of rotational symmetry.
The objective 100 is rotational symmetric and has one straight optical axis AX common to all refractive and reflective optical components. There are no folding mirrors. The concave mirrors have small diameters allowing to bring them close together and rather close to the intermediate images lying in between. The concave mirrors are both constructed and illuminated as off-axis sections of axial symmetric surfaces. The light beam passes by the edges of the concave mirrors facing the optical axis without vignetting.
The projection objective 100 is designed as an immersion objective for λ=193 nm having an image side numerical aperture NA=1.2 when used in conjunction with the high index immersion fluid, e.g. pure water, between the exit surface of the objective closest to the image surface IS, and the image surface IS. The refractive first objective part OP1 has spherical lenses only. Both concave mirrors CM1, CM2 are aspherical mirrors. The third objective part OP3 has one aspheric surface (entrance surface of lens L3-9) near the position of the pupil surface P3 of that objective part (where the chief ray CR of the imaging intersects the optical axis AX) and a second aspheric surface on the exit side of the penultimate lens L3-12 immediately upstream of the last, image side plano-convex lens L3-13. The last lens, which will be in contact with an immersion fluid during operation of the projection objective, is also denoted “immersion lens” in this specification. Although the projection objective is not fully corrected for all aberrations, it shows that an imaging is possible with a small number of aspheric lenses (NAS=2) all placed in the third objective part.
The projection objective 200 is designed as an immersion lens for λ=193 nm having an image side numerical aperture NA=1.20 when used in conjunction with a high index immersion fluid, e.g. pure water, between the exit surface of the objective and the image surface. The specification for this design is summarized in Table 2. The leftmost column lists the number of the refractive, reflective, or otherwise designated surface, the second column lists the radius, r, of that surface [mm], the third column lists the distance, d [mm], between that surface and the next surface, a parameter that is referred to as the “thickness” of the optical element, the fourth column lists the material employed for fabricating that optical element, and the fifth column lists the refractive index of the material employed for its fabrication. The sixth column lists the optically utilizable, clear, semi diameter [mm] of the optical component. A radius r=0 in a table designates a planar surface (having infinite radius).
In the case of this particular embodiment, three surfaces (surfaces 9, 10, 18) are aspherical surfaces. Table 2A lists the associated data for those aspherical surfaces, from which the sagitta or rising height p(h) of their surface figures as a function of the height h may be computed employing the following equation:
p(h)=[((1/r)h2)/(1+SQRT(1−(1+K)(1/r)2h2))]+C1·h4+C2·h6+ . . . ,
where the reciprocal value (1/r) of the radius is the curvature of the surface in question at the surface vertex and h is the distance of a point thereon from the optical axis. The sagitta or rising height p(h) thus represents the distance of that point from the vertex of the surface in question, measured along the z-direction, i.e., along the optical axis. The constants K, C1, C2, etc., are listed in Table 2A.
It is remarkable that in this embodiment many aberrations are corrected to a high degree with a small number of lenses (NL=13) and only one aspheric lens (L3-4) in addition to the aspheric concave mirrors CM1, CM2. Particularly, all third-order and fifth-order aberrations are zero. The variation in telecentricity is corrected over the field. Higher-order (seventh-order and higher) distortion is corrected over the field. Pupil aberration on the image side is corrected so that the image side numerical aperture NA=1.2 is constant over the field. Two real rays are corrected on-axis and four aperture rays are corrected at an intermediate field point. Higher-order (seventh-order and higher) astigmatism is corrected at the edge of the field and at an intermediate field point. This correction status is obtained with an objective where the lens diameters of the third objective part (acting as a focusing lens group) are quite small, with 218 mm diameter for the largest lens. The first lens L3-1 of the third objective part has a relatively large geometrical distance to the vertex of the geometrically nearest mirror (first concave mirror CM1), where that axial mirror-lens-distance MLD is 90 mm. This is about 7.5% of the axial distance between object surface OS and image surface IS, this object-image distance also being denoted as “track length”. A large geometrical distance MLD between the image side first concave mirror CM1 and the first lens of the third objective part contributes to small lens diameters in the third objective part.
The last lens L3-9 on the image side (immersion lens) has a short radius (50 mm) of the spherical entrance surface, whereby small incidence angles are obtained at that surface.
The design can be optimized with regard to residual aberrations, where higher order Petzval curvature and higher order sagitta oblique spherical aberration appears to dominate. Adding one lens to the first objective part and/or providing one or more further aspheric surfaces can contribute to reduce the residual aberrations. An example of a further development of the design of
A fourth embodiment of a projection objective 400 is shown in
In preferred designs of the invention, distortion, astigmatism, Petzval curvature and telecentricity variation over the field can all be corrected to very high orders with a similar construction of the first objective part OP1 (serving as a relay system to form the first intermediate image IMI1) and only a few spherical lenses in addition to the aspheric mirrors.
It appears that two aspheric concave mirrors CM1, CM2 are important for obtaining good correction with a small number of aspheric lenses. Two aspheric mirrors generally allow to make a design that is corrected for two chief ray aberrations, like distortion and telecentricity variation, to very high orders. It appears that those two aberrations can be exactly corrected by the two aspheric mirrors if the aspheric deformations of that mirrors are set correctly. It is one remarkable aspect, that, in addition, the astigmatism and Petzval curvature can also be corrected to a high degree with an all-spherical first objective part OP1.
It appears that there are at least three characteristics, which, singly or in combination, can contribute to the positive properties of the design type with regard to aberration corrections. One aspect is that the concave mirrors may preferably be quite unequal in radius, compared to other embodiments where the concave mirrors CM1, CM2 are identical or almost identical. Further, it appears that quite a lot of coma at the intermediate images IMI1 and/or IMI2 facilitates correction with a small number of aspheric lenses. Also, the remarkably large air space (mirror-lens-distance MLD) between the vertex of the image side concave mirror CM1 and the first lens of the third objective part appears to contribute to that beneficial properties.
It appears that the object side and the image side and/or the projection objective, i.e. the first objective part OP1 and the third objective part OP3, can almost be designed independently. In particular, the third objective part (focusing lens group) can be designed for aperture aberrations without much concern for field aberrations, and then a first objective part being relatively simple in construction can be designed to compensate for field aberration, wherein that compensation might be obtained without aspheric lenses or with only a small number of aspheric lens, e.g. only one aspheric lens.
The previous embodiments show that designs are available having a fairly simple first objective part with only four or five lenses, where all lenses may be spherical. Such rather simple relay lens group can give correction for field aberrations to an extremely high order. Aperture aberrations are preferably corrected in the third objective part, which may also have a fairly simple construction with just a few aspherics, the number of aspheric lenses in third objective part preferably being higher than the number of aspheric lenses in the first objective part.
One double asphere DA is provided in the third objective part OP3 optically between a second intermediate image IMI2 and the pupil surface P3 of that objective part in a region of significantly increasing beam diameter. The double asphere is formed by the aspheric exit surface of positive lens L3-6 and the subsequent aspheric entry surface of the following positive meniscus lens L3-7 immediately adjacent thereto. The axial separation of the two aspheric surfaces is smaller than the thickness of the thinner lens L3-7 adjacent to the double asphere such that the aspheres are in close proximity. A complex radial distribution of refractive power is thereby obtained in a specific region of the beam, thereby contributing strongly to image correction.
The projection objective 1000 in
When replacement of an aspheric surface by spherical surfaces is considered, it appears that what most matters is the base spherical curvature. A spherical doublet may therefore be able to replace an aspheric surface—even a very high order aspheric.
The correction status of variants of embodiment 1000 ranges between 4, 5 and 6 milliwaves over the field. This indicates that this correction can be obtained with an all-spherical first objective part OP1 and that the complete design does not need many aspheric lenses (only 5 lens aspherics here) to obtain a good performance.
The specification of the catadioptric projection objective 1100 is given in tables 11, 11A. The embodiment is a good example to show that “double aspheres” having two pretty strong aspheric lens surfaces very close to each other may be a very powerful design component. Here, a double asphere DA formed by lenses L3-4 and L3-5 is found in the region of increasing beam diameter within the third objective part OP3, similar to the embodiments shown in
A further embodiment of a catadioptric immersion objective 1300 with NA=1.3 is shown in
The catadioptric immersion objective 1400 in
There are two double aspheres DA in the third objective part OP3, namely one double asphere formed by facing surfaces of negative lenses L3-1, L3-2 in the region of minimum lens diameter within the third objective part, and a subsequent double aspheric formed by facing surfaces of lenses L3-3 and L3-4 in the region of largest beam diameter increase between the second intermediate image IMI2 and the aperture stop AS, which is positioned between the region of largest beam diameter and the image surface IS. Like the embodiments of

It may be beneficial to place the second objective part OP2 geometrically closer to the image surface the higher the desired numerical aperture is. For convenience, the second objective part OP2, preferably consisting of two aspheric concave mirrors CM1, CM2 only, is also denoted “mirror group” in the following. In order to demonstrate this feature, a first optical axis length OAL1 is defined between the object surface OS and the vertex of the concave mirror CM2 geometrically closest to the object surface, and a third optical axis length OAL3 is defined between the vertex of the concave mirror (CM1) geometrically closest to the image surface and the image surface (see
Each projection objective described here has a high NA image side end where projection radiation exits the projection objective at an exit surface ES, which is preferably planar in order to allow a uniform distance between the exit surface and a planar substrate surface arranged at the image surface IS. The lens closest to the image surface and forming the exit surface ES, is denoted “last lens” LL here. Preferably, the last lens is a plano-convex positive lens having a curved entry surface ENS, which is spherically curved in most embodiments, and the planar exit surface ES. In order to obtain high NA it has been found useful to design the last lens such that large refractive power provided by the curved entry surface ENS is arranged as close as possible to the image surface.
Further, strong curvatures, i.e. small curvature radii of the entry surface ENS of the last lens LL appear desirable. If TLL is the thickness of the last lens on the optical axis (i.e. the axial distance between the entry surface ENS and the exit surface ES measured along the optical axis), RLL is the object side vertex radius of the last lens (i.e. the radius of the entry surface ENS), and DIALL is the optically free diameter of the entry surface of the last lens, then the parameters LL1=TLL/RLL and LL2=DIALL/RLL should preferably fall within certain limits. Particularly, it has been found useful if the conditions 1.1<LL1<2.2 holds for LL1. Preferably, the upper limit may be even smaller, such as 1.8 or 1.7 or 1.6. As parameter LL1 becomes unity for a hemispherical lens, where the center of curvature or the entry surface coincides with the exit surface, the condition regarding LL1 shows that non-hemispherical last lenses are preferred, where the center of curvature of the curved entry surface lies outside the last lens, particularly beyond the image surface.
Alternatively, or in addition, the condition 2.1<LL2<2.6 should preferably hold for LL2. The upper limit could be smaller, e.g. 2.5 or 2.4 or 2.3. The respective values for LL1 and LL2 are presented in table 18. If at least one of the above condition holds, strong positive power provided by the curved entry surface of the last lens is provided close to the image surface, thereby allowing a large image side numerical aperture NA to be obtained, particularly with NA>1.1 or NA>1.2, such as NA=1.3 or NA=1.35.
With regard to the correction status of the intermediate images IMI1, IMI2 it is found that in some embodiments both intermediate images are essentially focused (i.e. many aberrations are corrected to a high degree), whereas in other embodiments significant aberrations occur, particularly coma (compare
The correction of the sine condition of the entire objective is challenging particularly for objectives having very high image side NA. The correction of sine condition may be facilitated by coma in the intermediate image. If the imaging from the high NA image surface to the low NA object surface (i.e. in reverse direction when compared to the intended use of projection objectives in lithography) is considered, the third objective part (where radiation enters) provides an intermediate image having a certain correction status. Assuming that the spherical aberration of that imaging is corrected, then the intermediate image will be essentially free of coma, if the sine condition of that imaging would be corrected. In contrast, if the sine condition is not corrected, that intermediate image would have a significant amount of coma. If the intermediate image has a considerable amount of coma, correction of the sine condition in the third objective part is facilitated.
Now, imaging of the second intermediate image into the image surface in the intended direction (towards the high NA end) is considered. If the second intermediate image would have a good correction status, particularly without coma, then the entire correction of the sine condition would have to be effected by the third objective part imaging the second intermediate image onto the image surface. If, in contrast, a certain amount of coma is present in the second intermediate image, then the third objective part can be designed in a more relaxed manner since the correction of the sine condition can at least partly be effected by the objective parts optically upstream of the third objective part, i.e. the refractive relay system OP1 forming the first intermediate image, and the catoptric second objective part OP2. Therefore, it appears that designs where the correction of coma is distributed between the first refractive objective part OP1 and the third objective part OP3 may be beneficial when compared to objectives where each of that refractive objective part is independently corrected for coma.
As mentioned earlier, the invention allows to build high NA projection objectives suitable for immersion lithography at NA>1 with compact size.
Table 19 summarizes the values necessary to calculate the compactness parameters COMP1, COMP2, COMP3 and the respective values for these parameters for each of the systems presented with a specification table (the table number (corresponding to the same number of a figure) is given in column 1 of table 19). Further, the respective values for N1AS, N3AS, and ASR are shown.
Table 19 shows that preferred embodiments according to the invention generally observe at least one of the conditions given earlier indicating that compact designs with moderate material consumption are obtained according to the design rules laid out in this specification. Further, the particular values characterizing the aspheric lens number and distribution are shown.
In the following, further characteristic features of projection objectives according to the invention are summarized, where one or more of those features may be present in an embodiment of the invention. Parameters summarized in tables 20 and 21 are used to demonstrate these features.
In some embodiments, the chief ray of the imaging process takes a characteristic course. For demonstration purposes, a chief ray CR running from an outermost field point (furthest away from the optical axis AX) essentially parallel to the optical axis and intersecting the optical axis at three consecutive pupil surface positions P1, P2, P3, each within on of the imaging objective parts OP1, OP2, OP3, is drawn in bold line in
In the region between the two concave mirrors CM1, CM2, the chief ray crosses the optical axis at a high chief ray angle CRA (M), that angle preferably falling in the region between 58° and 75°, particularly between 60° and 72°. (see table 20).
With regard to the magnification provided by the imaging objective parts OP1, OP2, OP3 it appears that it is beneficial if the magnification β3 of the third objective part OP3 imaging the second intermediate image IMI2 at high reduction ratio onto the image surface should preferably fall within a range 0.11≦β3≦0.17. In order to obtain a desired overall reduction ratio (e.g. 1:4 or 1:5) the second objective part OP2 may contribute to the overall reduction by having a magnification ratio β2<1. Preferably, the mirror group forming the second objective part OP2 may be designed to have a moderate reducing effect characterized by 0.85≦β2<1. If the second objective part contributes to some extent to the overall reduction, the third objective part responsible for the major part of reduction can be designed in a more relaxed manner.
It appears that the refractive power (characterized by the focal length f) provided by the first two or three lenses on the entry side of the third objective part OP3 immediately after the second concave mirror CM2 may contribute to good performance by designing this entry group such that the overall refractive power of that entry group is negative. In the embodiments of
On the other hand, it appears that not many negative lenses should be present in the third objective part following the second concave mirror CM2, where that number N3NL of negative lenses is three or less than three in all embodiments (parameter K7a=YES in table 21), and is smaller than three in the embodiments of
Further, it appears to be beneficial if the optically free diameter DIA31 of the first lens L3-1 of the third objective part OP3 is significantly smaller than the diameter DIAAS of the aperture stop. Preferably, the diameter ratio DR=DIA31/DIAAS should be smaller than 0.9. More preferably, an upper value of 0.8, even more preferably an upper value of 0.7 should not be exceeded. Values for the diameter ratio DR are given in table 21.
Further, it has been found that it may be beneficial if more than 50% of all lenses after the second concave mirror (i.e. lenses of the third objective part) have an optically free diameter smaller than the diameter of the second intermediate image IMI2 following the second concave mirror CM2. This condition is fulfilled for all embodiments, as shown by parameter K10 in table 21.
Also, all lenses of the first, refractive objective part OP1 should preferably be smaller than the paraxial size of the first intermediate image. If this condition is fulfilled, parameter K9 in table 20 is fulfilled.
In order to provide strong positive refractive power for obtaining strong beam convergence at the high NA image end it is preferable if at least one of 8 and 9 consecutive lenses upstream of the image surface should have positive refractive power. This is exemplified by parameter K11 in table 21, which is “YES”=Y if the condition is fulfilled and “NO”=N if the condition is not fulfilled.
In this context it is worth to note that it appears beneficial for obtaining high NA, if the position of the aperture stop AS is in the region of convergent beam between the position of largest beam diameter within the third objective part OP3, and the image surface. This property is exemplified by the ratio AS-IS/TT shown in table 20, where AS-IS is the geometrical distance between the position of the aperture stop AS and the image surface IS, and TT is the “track length” of the objective, i.e. the geometrical distance between object surface and image surface. The ratio AS-IS/TT may fall in a range between 0.09 and 0.18 (see table 20).
This feature is particularly pronounced in embodiments of
Further characteristic features are evident from the course of the coma beam. Here, a “coma beam” refers to a beam emerging from an object field point furthest remote from the optical axis and transiting the aperture stop at the edge of the aperture. The coma beam therefore contributes to determining which lens diameters must be used. The angle included by this coma beam and the optical axis is denoted in “coma beam angle CBA” in the following. The angle of that beam after refraction at the last lens of the first objective part (upstream of the first intermediate image IMI1) is denoted CBA1, whereas the angle of the coma beam immediately upstream of the refraction at the first lens of the image side third objective part OP3 is denoted CBA3. The values of these angles are given in table 21. It appears that for both coma beam angles values of less than 5° may be beneficial (table 21).
As noted above, the chief ray intersects the optical axis at pupil surfaces P1, P2, P3 in the concatenated objective parts OP1, OP2, OP3. As the pupil surfaces within the first and third objective parts are accessible for setting an aperture stop, these positions are also denoted aperture positions. The beam diameter at the aperture stop, DIAAS and the beam diameter DIAP1 at the pupil surface P1 in the first objective part, conjugated to the position of the aperture stop, should fall within certain limits. The ratio DIAAS/DIAP1 should be larger than 1. Preferably the condition DIAAS/DIAP1>2 should be satisfied. (see table 21).
It is to be understood that all systems described above may be complete systems for forming a real image (e.g. on a wafer) from a real object. However, the systems may be used as partial systems of larger systems. For example, the “object” for a system mentioned above may be an image formed by an imaging system (relay system) upstream of the object plane. Likewise, the image formed by a system mentioned above may be used as the object for a system (relay system) downstream of the image plane.
