Office Action

§103 §112
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA DETAILED ACTION Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1, 6, 9-13 and 21-29 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. There is no support for the elected embodiment of figure 4A for the claimed limitation of “the plurality of dies comprising at least a first die, a second die, and a third die”, as recited in claim 1, because figure 4A depicts only three dies and the phrase “at least” must include more than three dies. There is no support for the elected embodiment of figure 4A for the claimed limitation of “the bounding box area occupying all of the area within the bounding box”, as recited in claims 1 and 14. There is no support for the elected embodiment of figure 4A for the claimed limitation of “the bounding box comprises a geometric shape comprises cross”, as recited in claim 29. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1, 6, 9-14, 19 and 21-29 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The claimed limitation of “the bounding box area occupying all of the area within the bounding box”, as recited in claims 1 and 14 is unclear as to how the bounding box area can occupy all of the area within the bounding box since the dies occupy part of the area within the bounding box. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1, 6, 9-14, 19 and 21-29 are rejected under 35 U.S.C. 103 as being unpatentable over Hu (9,543,249) view of Thottethodi et al. (2014/0177626). Regarding claims 1 and 14, Hu teaches in figures 5B, 10B and related text an integrated chip (the entire structure), comprising a first chip and a second chip, wherein the first chip and the second chip are packaged together and the first chip comprises: an interconnect layer RDL2 having edges; and a plurality of dies 541, 542 disposed on the interconnect layer, and the plurality of dies comprising at least a first die Chip8, a second die Chip4 and a third die Chip0; a bounding box forming a peripheral boundary encompassing the first die, the second die, and the third die, the bounding box enclosing a bounding box area on the interconnect layer, the bounding box area having each of the first die, the second die and the third die disposed thereon; the bounding box area occupying all of the area within the bounding box, and the interconnect layer also having an edge area outside and surrounding the bounding box area on the interconnect layer, the edge area disposed between the bounding box and the edges; wherein the first die Chip8 and the third die Chip0 are interconnected to one another through direct routing in the bounding box area on the interconnect layer without crossing another die, and wherein the second die Chip4 and the third die Chip0 are interconnected to one another through direct routing within the bounding box area on the interconnect layer without crossing another die. Hu does not teach that the first die and the second die are interconnected to one another through routing within the edge area. Thottethodi et al. teach in figure 2 and related text a first die 212 and a second die 205 are interconnected to one another through routing 222 within the edge area (since said edge area is located outside the box area, above second 205, and within the interconnect layer). Hu and Thottethodi et al. are analogous art because they are directed to circuits layout and one of ordinary skill in the art would have had a reasonable expectation of success to modify Hu because they are from the same field of endeavor. It would have been obvious to a person of ordinary skill in the art, before the effective filling date of the claimed invention, to interconnect the first die and the second die to one another through routing within the edge area, as taught by Thottethodi, in the device of Hu, in order to reduce the real state area of the device by using conventional Chip-On-Chip structure. Regarding claims 6 and 19, Hu teaches that the bounding box is a die top bounding box comprising a boundary formed by peripheral dies in the plurality of dies. Regarding claim 9, it would have been obvious to a person of ordinary skill in the art, before the effective filling date of the claimed invention, to determine the bounding box based on the peripheries of the plurality of dies defined by the sizes, shapes, and arrangements of the plurality of dies in the device of Hu, in order to optimize the size of the device according to requirements of the application in hand. Regarding claims 10-13, Hu teaches substantially the entire claimed structure, as applied to claim 1 including an interconnect layer is a redistribution layer, an interposer, a substrate, or wherein the plurality of dies are interconnected through routing by using the uBumps, but does not explicitly state that the packaging manner of the chip is fan-out packaging, CoWoS packaging, multi-chip module packaging, or wherein each of the plurality of dies comprises uBumps. It would have been obvious to a person of ordinary skill in the art, before the effective filling date of the claimed invention, to use the packaging manner of the chip to be fan-out packaging, CoWoS packaging, multi-chip module packaging, or wherein each of the plurality of dies comprises uBumps, in the device of Hu, in order to reduce the cost of making the device by conventional packaging. Regarding claims 21 and 24, Hu teaches in figure 10B and related text that the first die, the second die and the third die are each rectangular in shape, and the bounding box is rectangular and has boundaries that are parallel to respective outer edges of the first die, the second die and the third die. Regarding claim 22, Hu teaches in figure 10B and related text that in a first dimension the peripheral dies of the plurality of dies comprise the first die Chip8 and the second die Chip4, and in a second dimension orthogonal to the first dimension the peripheral dies of the plurality of dies comprises the third die Chip0 which extends further in the second dimension than either the first die or the second die. Regarding claim 23, Hu teaches in figure 10B and related text that the interconnect layer is rectangular and has a first set of parallel edges extending in the first dimension and a second set of parallel edges extending in the second dimension. Regarding claim 25, Hu teaches in figure 10B and related text that the bounding box is sized and dimensioned (arbitrarily chosen) to define a bounding perimeter encompassing the entirety of the first die, the entirety of the second die and the entirety of the third die, a first portion of the bounding perimeter being coincident (arbitrarily chosen) with an outer edge of the first die, a second portion of the bounding perimeter being coincident with an outer edge of the second die, a third portion of the bounding perimeter being coincident with an outer edge of the third die. Regarding claims 26-28, Hu teaches in figure 10B and related text that the bounding box comprises a geometric shape that encloses or surrounds the combination of areas the plurality of dies occupy, and wherein the geometric shape is a parallelepiped, and wherein the parallelepiped comprises a rectangle. Regarding claim 29, Hu teaches in figure 10B and related text that the geometric shape comprises a cross. Response to Arguments Applicant’s arguments with respect to the claim(s) have been considered but are moot because of the new ground of rejection. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
