This disclosure relates generally to processing semiconductor components, and more particularly to processing sliders for hard disk drives.
Electronic devices, such as electronic data storage devices, including hard disk drives, are commonly used for storing and retrieving digital information. Some components of electrical devices, such as sliders having read/write heads, are made from semiconductor materials. Desirably, many semiconductor components are co-formed on a single wafer and then individually separated and further processed in subsequent manufacturing steps. Separating co-formed semiconductor components in a manner that promotes efficiency, accuracy, and lower costs can be challenging.
The subject matter of the present application has been developed in response to the present state of the art, and in particular, in response to the shortcomings of processes for manufacturing semiconductor components that have not yet been fully solved by currently available techniques. Accordingly, the subject matter of the present application provides apparatuses, systems, and methods for processing semiconductor components that overcome at least some of the above-discussed shortcomings of prior art techniques.
According to one embodiment, an apparatus, for processing semiconductor components, includes support surfaces and flexible couplings. The support surfaces are parallel to a first direction and spaced apart from each other in a second direction, perpendicular to the first direction. Moreover, the support surfaces are translationally movable relative to each other in the second direction to increase a pitch between adjacent support surfaces from a first pitch to a second pitch. Each of the flexible couplings is between and fixed to respective adjacent ones of the support surfaces. The flexible couplings flex as the support surfaces translationally move relative to each other in the second direction.
In one implementation, the apparatus further includes a linear actuator fixed to one of the support surfaces. The linear actuator is selectively operable to translationally move the support surfaces relative to each other in the second direction.
According to another implementation of the apparatus, adjacent support surfaces are co-movable in the second direction via the flexible coupling between and fixed to the adjacent support surfaces.
In some implementations of the apparatus, the support surfaces are translationally movable relative to each other in a third direction, opposite the second direction, to decrease the pitch from the second pitch to the first pitch. Adjacent support surfaces are co-movable in the third direction via the flexible coupling between and fixed to the adjacent support surfaces. The flexible couplings flex as the support surfaces translationally move relative to each other in the third direction. The flexible couplings can expand as support surfaces translationally move relative to each other in the second direction. In contrast, the flexible couplings can compress as support surfaces translationally move relative to each other in the third direction.
According to certain implementations, the apparatus also includes at least one locking element. The at least one locking element includes spacers having a third pitch between adjacent spacers, where the third pitch is equal to the second pitch. The at least one locking element is movable relative to the support surfaces to position respective spacers between adjacent support surfaces at the second pitch. The at least one locking element can be translationally movable in the first direction relative to the support surfaces to position respective spacers between adjacent support surfaces at the second pitch. Alternatively, the at least one locking element can be rotationally movable relative to the support surfaces to position respective spacers between adjacent support surfaces at the second pitch. For locking elements that are rotationally movable, the spacers of the at least one locking element are separated into groupings of spacers adjacent each other in the second direction along the at least one locking element, where each spacer of each grouping of spacers has a circumferential length different than each spacer of others of the groupings of spacers, and a circumferential length of each spacer of any grouping of spacers is greater than a circumferential length of each spacer of any adjacent grouping of spacers in the second direction.
In another embodiment, a system for processing semiconductor components includes a fixture and a first tray. The fixture includes a frame, support surfaces, and flexible couplings. The support surfaces are movably coupled to the frame, parallel to each other in a first direction, spaced apart from each other in a second direction, perpendicular to the first direction, and translationally movable relative to each other in the second direction to increase a pitch between adjacent support surfaces from a first pitch to a second pitch. Each of the flexible couplings is between and fixed to respective adjacent ones of the support surfaces. The flexible couplings flex as the support surfaces translationally move relative to each other in the second direction. The first tray includes receptacles that have a fourth pitch between adjacent receptacles. The fourth pitch is equal to the second pitch. The first tray is releasably coupleable to the frame.
According to some implementations of the system, the first tray further includes first apertures each formed in a respective one of the receptacles. The system may also include a first vacuum base that is relasably coupleable to the first tray and includes at least one fluid conduit communicatively coupled with the first apertures of the first tray when the first vacuum base is releasably coupled to the first tray. Additionally, the system can include a vacuum that is communicatively coupleable with the at least one fluid conduit of the first vacuum base and operable to draw air from the receptacles of the first tray via the first apertures of the first tray and the at least one fluid conduit of the first vacuum base when the vacuum is communicatively coupled with the at least one fluid conduit of the first vacuum base and the first vacuum base is releasably coupled to the first tray. The system can further include a second tray that includes receptacles having a fifth pitch between adjacent receptacles, where the fifth pitch is equal to the second pitch. The second tray is releasably coupleable to the first tray. The second tray can further include second apertures each formed in a respective one of the receptacles of the second tray. The system may additionally include a second vacuum base that is relasably coupleable to the second tray and includes at least one fluid conduit communicatively coupled with the second apertures of the second tray when the second vacuum base is releasably coupled to the second tray. The vacuum may be communicatively coupleable with the at least one fluid conduit of the second vacuum base and operable to draw air from the receptacles of the second tray via the second apertures of the second tray and the at least one fluid conduit of the second vacuum base when the vacuum is communicatively coupled with the at least one fluid conduit of the second vacuum base and the second vacuum base is releasably coupled to the second tray.
According to yet another embodiment, a method of processing semiconductor components includes coupling a row of semiconductor components on support surfaces, spaced at a first pitch between adjacent surfaces, such that the row of semiconductor components extends in a second direction and each semiconductor component of the row of adjoined semiconductor components is supported by a respective one of the support surfaces. The semiconductor components of the row of semiconductor components are adjoined. The support surfaces are parallel to each other in a first direction, perpendicular to the second direction, and spaced apart from each other in the second direction. The method also includes disjoining semiconductor components of the row of semiconductor components while positioned on the support surfaces, at the first pitch, at locations coincident with gaps defined between the support surfaces. Additionally, the method includes, after disjoining the semiconductor components of the row of semiconductor components, translationally moving the support surfaces relative to each other in the second direction to increase a pitch between adjacent support surfaces from the first pitch to a second pitch.
In some implementations, the method further includes releasably locking the support surfaces in place at the second pitch by positioning a spacer in each of the gaps defined between the support surfaces. Positioning the spacer in each of the gaps defined between the support surfaces may include separately positioning groupings of spacers in the gaps in sequence along the support surfaces in the second direction.
According to certain implementations, the method additionally includes releasably coupling a first tray, that includes receptacles having the second pitch between adjacent receptacles, with the support surfaces, at the second pitch, such that each receptacle is aligned with a respective one of the semiconductor components in a fourth direction perpendicular to the first and second directions. The method also includes, with the first tray releasably coupled with the support surfaces, washing the first tray, support surfaces, and semiconductor components to decouple the semiconductor components from the support surfaces. Furthermore, the method includes transferring each of the semiconductor components decoupled from the support surfaces to within respective receptacles of the first tray. The method may additionally include applying negative pressure to the semiconductor components within the receptacles of the first tray to retain the semiconductor components within the receptacles of the first tray. Also, the method may include, while applying the negative pressure to the semiconductor components within the receptacles of the first tray, decoupling the support surfaces from the first tray. Additionally, the method can include, after decoupling the support surfaces from the first tray, releasably coupling a second tray, that includes receptacles having the second pitch between adjacent receptacles, with the first tray such that each semiconductor component within the receptacles of the first tray is aligned with a respective one of the receptacles of the second tray in a fifth direction opposite the fourth direction. The method can also include transferring the semiconductor components from within the receptacles of the first tray to within respective receptacles of the second tray, applying negative pressure to the semiconductor components within the receptacles of the second tray to retain the semiconductor components within the receptacles of the second tray, and, while applying the negative pressure to the semiconductor components within the receptacles of the second tray, decoupling the first tray from the second tray.

Referring to
The frame 103 defines a cavity in which the expansion mechanism 104 is located. The cavity of the frame 103 has at least one open side contiguous with the engagement surface 124. Accordingly, the expansion mechanism 104 is accessible via the open end of the frame 103. The cavity of the frame 103 has an additional side, opposite the open side, which can be open or closed.
The expansion mechanism 104 includes an expandable portion 106, and a first end plate 108 and a second end plate 110. The expandable portion 106 is fixed to and interposed between the first end plate 108 and the second end plate 110. The first end plate 108 is movable relative to the frame 103, and the second end plate 110 is non-movable relative to the frame 103. Furthermore, the expandable portion 106 includes a plurality of support surfaces 112. Each of the support surfaces 112 is rigid and elongate. For example, each of the support surfaces 112 can be made from a metal, such as stainless steel, and can have a length greater than a width. The support surfaces 112 are arranged parallel to and spaced apart from each other between the first end plate 108 and the second end plate 110. Moreover, when the expansion mechanism 104 is supported by the frame 103, the support surfaces 112 extend lengthwise parallel to a first direction 115 and are spaced-apart from each other in a direction parallel to a second direction 114, which is perpendicular to the first direction 115. A gap 113 (shown in
The gaps 113 correlate with a pitch of the support surfaces 112. More specifically, the pitch of the support surfaces 112 is based on the minimum distance between adjacent support surfaces 112. As defined herein, a pitch of objects is the minimum distance between one point on an object and the corresponding point on an adjacent object. Accordingly, the pitch of the support surfaces 112 is the minimum distance between one point on a support surface 112 and the corresponding point on an adjacent support surface 112. Generally, the higher the minimum distance between adjacent support surfaces 112, the higher the pitch of the support surfaces 112, and the lower the minimum distance between adjacent support surfaces 112, the lower the pitch of the support surfaces 112. Accordingly, expanding the expandable portion 106, from a retracted state to an expanded state to increase the gaps 113, also increases the pitch of the support surfaces 112.
The expandable portion 106 of the expansion mechanism 104 also includes a plurality of flexible couplings 141 each positioned between and fixed to respective adjacent support surfaces 112. Each of the flexible couplings 141 couples together respective adjacent support surfaces 112. In this manner, the support surfaces 112 of the expandable portion 106 are flexibly linked together by the flexible couplings 141. Referring to
The flexible couplings 141 promote sequential relative movement of the support surfaces 112. Due to the flexible interconnectivity between support surfaces 112 provided by the flexible couplings 141, as one support surface 112 is translationally moved in a given direction, such as parallel to the second direction 114, to expand the expansion mechanism 104, the adjacent support surface 112 correspondingly translationally moves. Accordingly, by moving one support surface 112 in the given direction, all support surfaces 112 move in the given direction in a sequential manner by virtue of the flexible interconnectivity provided by the support surfaces 112.
Although in the example of
In some implementations, one or two webs 143 may be positioned between and fixed to a support surface 112, at a first end of the expandable portion, and the first end plate 108, to flexibly couple together the support surface 112, at the first end of the expandable portion 106, and the first end plate 108. Similarly, one or two webs 143 may be positioned between and fixed to a support surface 112, at a second end of the expandable portion 106, and the second end plate 110, to flexibly couple together the support surface 112, at the second end of the expandable portion 106, and the second end plate 110. In such implementations, expansion and retraction of the expandable portion 106 can be facilitated by moving the first end plate 108 relative to the second end plate 110 in opposite directions. For example, moving the first end plate 108, relative to the second end plate 110, in the second direction 114, expands the expandable portion 106 and moving the first end plate 108, relative to the second end plate 110, in a direction opposite the second direction 114 retracts the expandable portion 106.
Returning to
The linear actuator 126 may be at least partially supported by the frame 103. For example, for a manually-operated linear actuator, the frame 103 may include an aperture through which a portion of the linear actuator 126 extends and on which the linear actuator 126 is supported as the linear actuator 126 is translationally moved. Furthermore, to help facilitate gripping of a manually-operated linear actuator, the linear actuator 126 may include a knob, or other gripping feature, that a user may grip when translationally moving the linear actuator 126.
The fixture 102 also includes one or more linear rails 116 fixed to the frame 103 and non-movable relative to the frame 103. The linear rails 116 are parallel to each other and to the second direction 114. The expansion mechanism 104 is supported on and movable translationally along the linear rails 116. In this manner, the linear rails 116 help to promote translational movement of the expandable portion 106 of the expansion mechanism 104 in the second direction 114 and third direction, opposite the second direction 114, without binding of the expandable portion 106. The expansion mechanism 104 includes two channels that extend through the first end plate 108 and at least a portion of the expandable portion 106. Each of the linear rails 116 extends through a respective of the channels of the expansion mechanism 104 to retain the first end plate 108 and expandable portion 106 on the linear rails 116.
Additionally, the fixture 102 includes at least one locking element 120 that is configured to lock the expandable portion 106 of the expansion mechanism 104 in the expanded state. In some embodiments, the fixture includes two locking elements 120 positioned on opposite sides of the expandable portion 106. The locking elements 120 are movably fixed to the frame 103 of the fixture 102. Each locking element 120 includes spacers 144 that are spaced apart at a third pitch corresponding with a desired pitch between the support surfaces 112 in the expanded state. The spacers 144 are sized to fit within the gaps 113 between the support surfaces 112, with each spacer 144 fitting within a respective one of the gaps 113. Moreover, when positioned within the gaps 113, the spacers 144 are sized to, at least indirectly, engage the support surfaces 112 to maintain the desired pitch between the support surfaces 112. The spacers 144 can have any of various shapes. In some implementations, each of the spacers 144 is tooth-shaped or wedge-shaped to promote centering of the spacers 144 within respective gaps 113 as the spacers 144 are inserted into the respective gaps 113. Insertion of the spacers 144 of the locking elements 120 into the gaps 113 is accomplished by actuation of the locking elements 120. The locking elements 120 can be actuated automatically or manually.
In the embodiments of
The spacers 144 of the same grouping of spacers 142 have the same circumferential length and are arranged on the same circumferential portion of the shaft 121 of a locking element 120. Moreover, the circumferential length of the spacers 144 of one grouping of spacers 142 is different than the circumferential length of the spacers 144 of an adjacent grouping of spacers 142. In one implementation, as shown, the circumferential length of the spacers 144 of one grouping of spacers 142 is more than the circumferential length of the spacers 144 of an adjacent grouping of spacers 142 in the second direction 114. In other words, in the second direction 114, the circumferential length of the spacers 144 from grouping of spacers 142 to grouping of spacers 142 incrementally decreases. Furthermore, despite the differing circumferential lengths of the spacers 144, the circumferential location of the spacers 144 on the shaft 121 for each grouping of spacers 142 is aligned along an axis of the shaft 121. For example, in one implementation, as shown, the groupings of spacers 142 are arranged in a step-wise manner along the shaft 121.
In operation, after the expandable portion 106 is expanded into the expanded state, the locking elements 120 of
Generally, with the expandable portion 106 of the expansion mechanism 104 in the retracted state (see, e.g.,
In certain implementations, each row 130 of semiconductor components 132 is separated from a plurality of semiconductor components 132 co-formed on a wafer. For example, the wafer may include an array of semiconductor components 132 across the surface of the wafer. The semiconductor components 132 may be categorized into one of several quads of semiconductor components 132 with each quad having a given number of rows of semiconductor components with a given number of semiconductor components per row. Generally, to increase the number of semiconductor components 132 manufactured per batch, and thus reduce costs and labor, the areal density of semiconductor components on the wafer desirably is maximized (e.g., the pitch between adjacent semiconductor components of a given row is minimized). After the semiconductor components 132 are formed on the wafer, the rows 130 of semiconductor components 132 are formed by physically separating semiconductor components 132, arranged in rows on the wafer, from each other. The rows 130 are physically separated by a cutting process, such as with a knife, cutting wheel, laser, etc., in some implementations, or by an additional or alternative separation process in other implementations.
The semiconductor components 132 can be any of various components used for any of various applications. In one embodiment, each semiconductor component 132 is a slider for a hard disk drive or other magnetic recording medium device. The slider includes an integrated circuit for providing magnetic-bit reading capabilities and magnetic-bit writing capabilities. The semiconductor components 132 can be made from any of various semiconductor materials, such as silicone. In yet other embodiments, the semiconductor components 132 can be made from materials other than semiconductor materials.
Generally, as will be described in more detail below, after the rows 130 of semiconductor components 132 are fixed on the support surfaces 112 in the retracted state, the semiconductor components 132 of each row 130 are physically separated or disjoined from each other. When the semiconductor components 132 of each row 130 are physically separated from each other, the support surfaces 112 can be moved relative to each other in the second direction 114 into the expanded state (see, e.g.,

After the semiconductor components 432 of the row 430 are disjoined, as shown in
With the expansion mechanism 404, having the disjoined semiconductor components 432 coupled thereto, in the expanded state, a first tray 470A of the system 400 can be releasably coupled to the fixture 402 via engagement between the engagement surface 424 of the frame 403 and an engagement surface 481A of the first tray 470A. The first tray 470A includes receptacles 476A, separate and distinct from each other, spaced apart from each other at a fourth pitch equal to the second pitch P2. Accordingly, with the first tray 470A coupled to the fixture 402, the semiconductor components 432 are at least partially positioned within a respective one of the receptacles 476A.
In some implementations, due the material and manufacturing limitations, the fourth pitch between the receptacles 476A of the first tray 470A is the smallest pitch possible. However, as presented above, the semiconductor components 432 can be and are desirably manufactured to have a first pitch P1 smaller than the fourth pitch. Accordingly, providing a fixture 402 that enables the increase of the pitch of the semiconductor components 432 from the first pitch P1 to the second pitch P2, which can be equal to the fourth pitch of the receptacles 476A, allows the semiconductor components 432 to be manufactured at a relatively smaller pitch, while ensuring compatibility with manufacturing process equipment having a relatively larger pitch.

While the vacuum 484 applies the negative pressure to the semiconductor components 432 within the receptacles 476A of the first tray 470A, the fixture 402, including the support surfaces 412, is decoupled from the first tray 470A. The application of negative pressure to the semiconductor components 432, while decoupling the fixture 402 from the first tray 470A, helps to ensure the semiconductor components 432 are retained within the receptacles 476A of the first tray 470A and do not remain on the fixture 402, such as due to any residual bonding agent left over after the washing process, as the fixture 402 is removed from the first tray 470A.
In some implementations, after the fixture 402 is removed from the first tray 470A, the upward-facing surfaces of the semiconductor components 432 within the receptacles 476A of the first tray 470A can be further processed, such as polished and/or etched. However, according to certain implementations, it may be desirable to further process the downward-facing surfaces of the semiconductor components 432 within the receptacles 476A of the first tray 470A.

In some implementations, the method 500 further includes (block 508) releasably locking the support surfaces in place at the second pitch by positioning a spacer in each of the gaps defined between the support surfaces. Positioning the spacer in each of the gaps defined between the support surfaces may include separately positioning groupings of spacers in the gaps in sequence along the support surfaces in the second direction. Also, the method 500 may include (block 510) releasably coupling a first tray, comprising receptacles at the second pitch, with the support surfaces, at the second pitch, such that each receptacle is aligned with a respective one of the semiconductor components in a fourth direction perpendicular to the first and second directions, washing the first tray, support surfaces, and semiconductor components to decouple the semiconductor components from the support surfaces, and transferring each of the semiconductor components decoupled from the support surfaces to within respective receptacles of the first tray. The method 500 can also include (block 512) applying negative pressure to the semiconductor components within the receptacles of the first tray to retain the semiconductor components within the receptacles of the first tray and decoupling the support surfaces from the first tray. Furthermore, the method 500 may include (block 514) releasably coupling a second tray, that includes receptacles at the second pitch, with the first tray such that each semiconductor component within the receptacles of the first tray is aligned with a respective one of the receptacles of the second tray in a fifth direction opposite the fourth direction, transferring the semiconductor components from within the receptacles of the first tray to within respective receptacles of the second tray, applying negative pressure to the semiconductor components within the receptacles of the second tray to retain the semiconductor components within the receptacles of the second tray, and decoupling the first tray from the second tray.
