Description




BACKGROUND OF THE INVENTION




Field of the Invention




The present invention relates to an electronic component with a semiconductor chip and a method for fabricating the electronic component.




In the fabrication of electronic components with semiconductor chips, rewiring plates are often employed, which are glued onto the active surface of the semiconductor chip such that a through-hole remains clear. The through-hole serves for providing a bond channel, so that after the gluing process, bond wires can be bonded from contact surfaces on the semiconductor chip to contact terminal pads on the rewiring plate. After the bond connections are glued and attached, the bond channel (i.e. the through-hole in the rewiring plate) is covered with a plastic compound.




As miniaturization of the semiconductor chips progresses and integration increases, the number of contact surfaces on the chip tends to rise. But the component size should not grow as chips become smaller. Therefore, the density of interconnects per area on the rewiring plate increases. In order to accommodate more contact terminal pads in the bond channel, they can be configured in two or more rows, although this requires a wider bond channel and thus reduces the area available for the rewiring tracks.




SUMMARY OF THE INVENTION




It is accordingly an object of the invention to provide an electronic component with a semiconductor chip and a method for producing the electronic component which overcome the above-mentioned disadvantages of the prior art apparatus and methods of this general type.




In particular, it is an object of the invention to design an electronic component with a semiconductor chip that makes it possible to produce reliable bond connections in order to overcome the disadvantages of the prior art.




With the foregoing and other objects in view there is provided, in accordance with the invention, a method for fabricating an electronic component, which includes steps of: providing a semiconductor chip having an active front side with semiconductor structures and contact surfaces configured such that a first portion of the contact surfaces extend in two parallel rows, and at least a second portion of the contact surfaces extend in one row; providing a rewiring plate with an oblong through-hole forming a bond channel and with a rewiring plane facing away from the semiconductor chip; providing the rewiring plane with contact terminal pads, rewiring lines, and external contact surfaces; fastening the semiconductor chip on the rewiring plate, such that the contact surfaces of the semiconductor chip are positioned in the through-hole of the rewiring plate; producing bond connections between the contact surfaces on the semiconductor chip and the contact terminal pads on the rewiring plate; and filling the through-hole with a plastic compound to embed the bond connections.




In accordance with an added mode of the invention, the method includes steps of: providing the bond connections with bond wires that cross longitudinal sides of the through-hole and providing the bond wires with approximately uniform wire lengths.




With the foregoing and other objects in view there is also provided, in accordance with the invention, an electronic component, including: a semiconductor chip having an active front side with semiconductor structures and contact surfaces; a rewiring plate having a rewiring plane with contact terminal pads; and bond connections between the contact surfaces on the active front side and the contact terminal pads. The rewiring plane faces away from the semiconductor chip. The active front side of the semiconductor chip is fastened on the rewiring plate. The rewiring plate is formed with an oblong through-hole for receiving the bond connections. The through-hole has a first portion in which the contact surfaces extend in two parallel rows. The through-hole has at least one additional portion, for example, a second portion in which the contact surfaces extend one row.




This configuration of contact surfaces makes possible a partly narrowed contour of the through-hole and thus makes more space available at the narrowed locations for terminal pads of the rewiring plane.




In a first embodiment of the invention, the contact surfaces are arranged in two parallel rows in a central first portion and in only one row in peripheral second and third portions, respectively.




In the center first region of the through-hole, the contact surfaces of the semiconductor chip extend in two parallel rows, because more space is available on the rewiring plate for contact terminal pads. In contrast, in the peripheral second and third portions, the contact surfaces extend in only one row, because here there tends to be less space available for contact terminal pads. The contact terminal pads in electrical contact with the contact surfaces extending in second and third portions thus have sufficient space in this configuration.




In an alternative embodiment of the invention, the contact surfaces are arranged in one row in the central first portion and in two parallel rows in the peripheral second and third portions, respectively.




This way, there is less space available on the rewiring plate for contact terminal pads in the peripheral second and third portions, where the contact surfaces of the semiconductor chip extend in two parallel rows. On the other hand, in this embodiment the contact surfaces extend in only one row in the middle first portion, so that more space is available for contact terminal pads at this location. The contact terminal pads which are in electrical contact with the contact surfaces extending in the first portion therefore have sufficient space in this configuration.




An inventive embodiment provides that the semiconductor chip includes edge sides and a back side opposite the active front side. It is further provided that the contact surfaces on the active front side have a structure and configuration to which the through-hole of the rewiring plate is adapted.




This inventive embodiment has the advantage that, in the peripheral regions, sufficient area remains between the through-hole and external contacts, such that conductive tracks of the rewiring structure can be led between them.




According to another embodiment of the invention, the contact surfaces on the semiconductor chip are electrically connected to contact terminal pads on the rewiring plate by bond connections, and the contact terminal pads are electrically connected by rewiring lines and external contact surfaces of the electronic component.




The particular advantage of this embodiment is that fast and inexpensive electrical connections can be produced by using the bond connections. The through-hole in the rewiring plate is advantageously a bond channel.




According to another embodiment of the invention, the through-hole in the rewiring plate has an oblong contour. A central first region of the through-hole corresponds to the contact surfaces that are arranged in the central first portion, and peripheral second and third regions of the through-hole respectively correspond to the contact surfaces arranged in the second and third portions. It is further provided that the through-hole has a narrowed contour in the second and third regions compared to its contour in the first region.




The advantage of this embodiment is that sufficient space is available for the rewiring structure that is arranged on the rewiring plate between contact terminal pads and the external contacts. The contact terminal pads can thus be constructed large enough that reliable bond connections can always be installed on them.




In another inventive embodiment, the bond connections including bond wires on the long sides of the through-hole have approximately uniform wire lengths, which advantageously enables rapid and reliable bonding. The approximately equal bond wire lengths also guarantee an approximately uniform height of the bond connections and thus a sufficiently flat electronic component.




According to an inventive embodiment, the contact terminal pads respectively adjoin the long sides of the through-hole and have approximately equal area dimensions. This guarantees a reliable bond connection on any contact terminal pad at any time.




A typical rewiring plate thickness is between 150 μm and 300 μm. The purpose of the rewiring plate is to transmit electrical signals and to supply currents of the semiconductor chip from the microscopic contact terminal pads to macroscopic external contact surfaces via conductive tracks. In this context, the term “microscopic dimensions” refers to structures that can be measured only under a light microscope, and the term “macroscopic” refers to structures that can be recognized with the naked eye.




According to another embodiment of the invention, the rewiring plate includes a fiber-reinforced plastic plate with a metal laminate that is structured into contact terminal pads, rewiring lines, and external contact surfaces. The fiber reinforcement gives this embodiment the advantage that, when packaging the electronic component in a plastic housing, the rewiring plate retains its dimensional stability and can therefore withstand the high injection pressure. This injection pressure is in the order of between 8 MPa and 15 MPa. The structured metal laminate is installed on the bottom side of the rewiring plate and is protected from metallization during the soldering of the external contacts by a solder resist layer. Only the external contact surfaces are kept clear of both the solder resist and the plastic compound until the external contacts are installed.




In another embodiment of the invention, the metal laminate consists of copper or a copper alloy. The advantage of this is that the metal laminate can be galvanically applied on the fiber-reinforced plastic of the rewiring plate, and copper represents a relatively inexpensive metal laminate relative to the material costs.




Because copper surfaces oxidize easily and are therefore suitable for neither bonding nor soldering, the contact terminal pads on which bond connections will be produced and the external contact surfaces onto which the external contacts will be soldered are respectively furnished with a bondable or solderable coating in another embodiment of the invention.




The inventive method for fabricating one of the above described embodiments of the above described electronic component includes the following steps: A first semiconductor chip is provided with contact surfaces on an active front side. A rewiring plate is provided with an oblong through-hole that forms a bond channel, and with a rewiring plane consisting of contact terminal pads, rewiring lines and external contact surfaces. The semiconductor chip is fastened on the rewiring plate such that the contact surfaces of the semiconductor chip are positioned in the through-hole of the rewiring plate. Bond connections are then produced between the contact surfaces on the semiconductor chip and the contact terminal pads on the rewiring plate. Lastly, the through-hole is filled with a plastic compound, embedding the bond connections.




The particular advantage of this inventive method is that compact electronic components can be reliably produced using the method.




According to an embodiment of the inventive method, an approximately uniform wire length is maintained in the installation of the bond connections with the bond wires on the long sides of the through-hole. This is associated with the advantage that stable and flat bond connections can be produced, which results in a flat electronic component.




In summary, the invention has the following aspects: In order to be able to provide the semiconductor chips, which are becoming increasingly smaller with the progress of miniaturization, and whose external contacts (e.g. contact bumps or the like for what are known as ball grid arrays) continue to remain the same size, with a reliable rewiring, the contact terminal pads on the rewiring plane must have a certain minimum size. Otherwise, it is difficult to contact the bonds, which can lead to a declining reliability of the contacts. The higher-density semiconductor chips require more conductive tracks inside the rewiring plane. In order to make sufficient space available for them, the contact surfaces of the semiconductor chip can be arranged in only one row (what is known as a single pad row), and the bond channel can be accordingly constructed narrowly.




In order to be able to construct sufficiently large contact terminal pads of the rewiring structure, the contact surfaces of the semiconductor chip are inventively arranged in one or two rows by section, i.e. in a combination of single and double pad rows. In non-critical regions where there is sufficient space available for placing the contact terminal pads, i.e. in central regions, the contact surfaces are arranged in two rows. This way, a large number of bond connections can be led on a relatively small space. On the other hand, in the extreme regions, the contact surfaces are arranged in only one row. The bond channel can accordingly be constructed narrower, and therefore sufficient area is left between the bond channel and the external contact surfaces (ball landing pads) for accommodating the conductive track structures.




This development does not require modifying the rewiring plate fabrication or the fabrication of the electronic components with semiconductor chips. A miniaturization of chips with suitable housings is possible without changing the technology and without extra costs.




Other features which are considered as characteristic for the invention are set forth in the appended claims.




Although the invention is illustrated and described herein as embodied in an electronic component with a semiconductor chip and fabrication method, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.




The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring now to the figures of the drawing in detail and first, particularly, to

FIG. 1

thereof, there is shown a schematic bottom view of a first embodiment of an electronic component that does not have a plastic covering on a through-hole


81


for a bond channel


86


. The bottom side of the electronic component


2


is formed by a rewiring plate


8


(See FIG.


8


), whose outer boundary or edges are not represented for viewing purposes. An active front side


41


of a semiconductor chip


4


can be seen in

FIG. 1

in the region of the through-hole


81


. This through-hole


81


has been installed in the rewiring plate


8


, but has not yet been covered by a plastic covering, for easier viewing. The arrangement of contact surfaces


43


of the semiconductor chip


4


is thus visible on the active front side


41


in the through-hole


81


.




These contact surfaces


43


are microscopic, and so they cannot be detected with the naked eye and have dimensions that can be determined only with a light microscope. These contact surfaces


43


in the through-hole


81


are connected to contact terminal pads


82


on the bottom side


93


of the rewiring plate


8


by bond connections


10


. The contact terminal pads


82


on the rewiring plate


8


also have microscopic dimensions and are connected by rewiring lines


84


to external contact surfaces


85


having macroscopic dimensions (i.e. which can be seen by the naked eye). External contacts, which are omitted from this representation in

FIG. 1

, can be attached to these external contact surfaces


85


.




This view clearly shows the bond channel


86


, which is partitioned into three regions


87


,


88


and


89


, and the contact surfaces


43


, which lie partly in two rows and partly in one row. In a middle first portion


44


, which corresponds to the first region


87


, the contact surfaces


43


lie in two opposite parallel rows. In peripheral second and third portions


45


,


46


, which correspond to second and third regions


88


,


89


of the through-hole


81


, the contact surfaces


43


lie in only one row, respectively. The through-hole


81


is narrowed in the second and third regions


88


,


89


relative to the middle first region


87


, so that the contact terminal pads


82


adjoining the long sides


91


of the through-hole


81


can also be constructed sufficiently large in the second and third regions


88


,


89


.




In order to achieve sufficiently large contact terminal pads


82


in the top and bottom peripheral region of the through-hole given the described configuration of the external contact surfaces


85


and given the required rewiring lines


84


, which occupy a minimum width, the recess is pinched at the ends bounding its longitudinal extent, which makes more space available for sufficiently large contact terminal pads


82


.





FIG. 2

represents a detailed section of the bottom half of

FIG. 1

, whereby the semiconductor chip


4


is additionally represented by a dotted line around the rewiring structure. The shape of the contact terminal pads


82


is especially clear in this enlarged view. These are constructed as large in the second region


88


of the through-hole


81


and in the third region


89


(which is not represented) as in the middle first region


89


. This is possible only because the through-hole


81


is constructed narrower in the second region


88


, and because the contact surfaces


43


in the second portion


45


are arranged in only one row. In the second portion


45


(and the third portion


46


, which is not represented), the bond connections


10


lead to contact terminal pads


82


on either side of the bond channel


86


in alternating fashion.





FIG. 3

is a schematic cross-section representing the first embodiment of the electronic component


2


along the line A—A of

FIG. 2

, but in which a plastic covering


12


has already been provided. Components that perform the same function as in

FIGS. 1 and 2

are identified by the same reference characters and are not elaborated upon.




The cross-section in

FIG. 3

along the line A—A of

FIG. 2

shows the basic concept of an electronic component as a BOC (Board On Chip) component. The bottom side of the electronic component


2


is simultaneously the bottom side


93


of the rewiring plate


8


, which consists of three layers, namely a fiber-reinforced plastic plate


96


, a structured copper laminate in the form of a rewiring plane


83


, and a structured solder resist layer


95


.




The structured copper laminate in the form of the rewiring plane


83


includes contact terminal pads


82


, rewiring lines


84


and external contact surfaces


85


, as already represented in

FIGS. 1 and 2

. The structured solder resist layer


95


leaves the external contact surfaces


85


and the contact terminal pads


82


clear, so that an external contact


14


can be installed on the external contact surfaces


85


as a contact ball or contact bump. Bond connections


10


in the form of bond wires


11


can be installed on the exposed contact terminal pads


82


, which wires connect the contact terminal pads


82


to contact surfaces


43


on the active front side


41


of the semiconductor chip


4


. The plastic covering


12


protects the bond wires


11


from mechanical and corrosive damage. In this embodiment of the invention, the external contact


14


is higher than the plastic covering


12


in order to guarantee that the external contact


14


has a sufficient over-elevation beyond the bottom side of the electronic component for giving contact.





FIG. 4

represents an alternative embodiment of the rewiring plane


83


, in which the contact terminal pads


82


at the extreme edges of the long sides


91


of the through-hole


81


are so small that reliable contacting using bond wires may already be problematic. The contact surfaces


43


of the semiconductor chip


4


are arranged in two parallel rows, so that the through-hole


81


must have a uniform width over its entire length. For this reason, given placement of the external contact surfaces


85


as above, and given the mandatory minimum widths of the rewiring lines, very little space is available in the edge regions of the through-hole


81


for contact terminal pads


82


.





FIG. 5

represents an alternative arrangement of the rewiring plane


83


, which has identically positioned external contact surfaces


85


as those in the embodiment shown in FIG.


4


. However, the contact surfaces


43


of the semiconductor chip


4


are constructed in two parallel rows only in a middle first portion


44


. On the other hand, in peripheral second and third portions


45


,


46


, the contact surfaces


43


are constructed in one row, which makes possible a more narrowly constructed through-hole


81


in these second and third regions


88


,


89


. The hole therefore leaves more space for contact terminal pads


82


, which are accordingly constructed larger. This way, a reliable contacting using bond wires


11


for the electrical connection between the contact terminal pads


82


and the contact surfaces


43


is always possible.




Thus, a miniaturization of semiconductor chips with suitable housings is also possible without changing the technology. The fabrication process for the substrate is not changed either.




Unlike the embodiments represented in the

FIGS. 1

to


5


, in an alternative development of the invention, the contact surfaces


43


in the central first portion


44


extend in only one row. It is also possible to lead the contact surfaces


43


in the peripheral second and third portions


45


,


46


in two parallel rows. The through-hole


81


is then wider in the second and third regions


88


,


89


than in the first region


87


, accordingly.




A method is provided for fabricating the electronic component


2


having a semiconductor chip


4


, which has an active front side


41


and semiconductor structures, on a rewiring plate


8


. The semiconductor chip


4


is fastened on the rewiring plate


8


. The rewiring plate


8


includes an oblong through-hole


81


for bond connections


10


between contact surfaces


43


on the active front side


41


and contact terminal pads


82


on a rewiring plane


83


of the rewiring plate


8


. The rewiring plane


83


faces away from the semiconductor chip


4


. The contact surfaces


43


extend in two parallel rows in a central first portion


44


and in one row in peripheral second and third portions


45


and


46


. The method includes the following steps: Upon providing a semiconductor chip


4


with contact surfaces


43


on its active front side


41


, which includes semiconductor structures, a rewiring plate


8


is provided with an oblong through-hole


81


that forms a bond channel


86


and with a rewiring plane


83


consisting of contact terminal pads


82


, rewiring lines


84


, and external contact surfaces


85


.




The semiconductor chip


4


is fastened on the rewiring plate


8


, with the contact surfaces


43


of the semiconductor chip


4


being positioned in the through-hole


81


of the rewiring plate


8


. Next, bond connections


10


are produced between the contact surfaces


43


on the semiconductor chip


4


and the contact terminal pads


82


on the rewiring plate


8


. Lastly, the through-hole


81


is filled with a plastic compound


12


, leaving the bond connections


10


embedded.




The bond connections


10


with the bond wires


11


on the long sides


91


of the through-hole


81


are advantageously attached such that approximately uniform wire lengths are maintained.
