Office Action

§102 §103 §112
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Claim Rejections - 35 USC § 112 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 appl icant regards as his invention. Claim 18 is 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 invent or or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 18, “ wherein the first substrate conductive pillar connects the first chip with the substrate ” in line s 1-3 is unclear . More specifically, claim 16 establishes this pillar is configured with the second chip (Claim 16: line 15: “a second chip disposed on the first chip, comprising a first protrusion”; and line 20: “a first substrate conductive pillar connecting the first protrusion with the first substrate”) . It is unclear how this pillar can simultaneously connect to 1) the first protrusion of the second chip, 2) the first substrate, and 3) the first chip. For the sake of compact prosecution, claim 18 is interpreted in the instant Office action consistent with the original disclosure, as follows: “ wherein the first substrate conductive pillar connects the first chip with the substrate ” in lines 1-3 is equivalent to “wherein the first substrate conductive pillar connects the second chip with the substrate” . This interpretation is to be confirmed by applicant in next office action.

Claim Rejections - 35 USC § 103 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, 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. Rejection Note: Italicized claim limitations indicate limitations that are not explicitly disclosed in the primary reference, but disclosed in the secondary reference(s). Claim s 6 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Oh as applied to claim 1 above, and further in view of Lee ( US 20210183817 A1 ) . Regarding claim 6, Oh discloses the semiconductor device according to claim 1 (Fig. 22) , but fails to teach it “further comprising: an interposer module , comprising: a second substrate; and a plurality of interposer conductive pillars formed on the second substrate, wherein each of the interposer conductive pillars has an end surface, and the end surfaces of the interposer conductive pillars are different in height; wherein one of the interposer conductive pillars is connected to one of the first substrate, the first chip and the second chip, and another of the interposer conductive pillars is connected to another of the first substrate, the first chip and the second chip” . Lee discloses a semiconductor device ( Fig. 1 ) further comprising: an interposer module (101) , comprising: a second substrate ([0024]: “a core material”) ; and a plurality of interposer conductive pillars (110) formed on the second substrate, wherein each of the interposer conductive pillars has an end surface ( See annotated figure) , and the end surfaces of the interposer conductive pillars are different in height (different in the vertical direction) ; wherein one of the interposer conductive pillars is connected to one of the first substrate (connected to first substrate 550, See “end surfaces” in annotated figure) , the first chip and the second chip, and another of the interposer conductive pillars is connected to another of the first substrate, the first chip and the second chip (connected to second chip 320, See “end surfaces” in annotated figure) . Modifying the semiconductor device of Oh by including the interposer module of Lee would arrive at the claimed device configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation, pillars and chips are connected to a substate in the same spatial orientation ( Oh: Fig. 22: pillars 50 and chips 3; Lee: Fig. 1: pillars 110 and chips 420/320/220 ) . Lee provides a teaching to motivate one of ordinary skill in the art before the effective filing date to include the interposer module in that it would increase strength of the device ( [0026]: “ may improve stiffness of the semiconductor package ” ) . Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed interposer module because it would increase strength of the device. MPEP 2143 (I)(G). Illustrated below is a marked and annotated figure of Fig. 1 of Lee. Regarding claim 8, Oh discloses the semiconductor device according to claim 1 (Fig. 22) , but fails to teach it “further comprising: an interposer module , comprising: a plurality of first circuit layers; a second circuit layer, wherein the second circuit layer and each of the first circuit layers are respectively located in different heights; a plurality of conductive vias connecting the first circuit layers with the second circuit layer; and a plurality of interposer conductive pillars, wherein one of the interposer conductive pillars is connected with one of the first circuit layers, and another of the interposer conductive pillars is connected with another of the first circuit layers” . Lee discloses a semiconductor device (Fig. 1) , further comprising: an interposer module (101) , comprising: a plurality of first circuit layers ( some of this plurality, [0025]: “ a plurality of wiring layers buried in the insulating layers ”. Note: Lee does not teach a specific number of wiring layers, but the examiner finds “a plurality” reasonably includes at least 3 wiring layers ) ; a second circuit layer ( another of this plurality, [0025]: “ a plurality of wiring layers buried in the insulating layers ”. Note: Lee does not teach a specific number of wiring layers, but the examiner finds “a plurality” reasonably includes at least 3 wiring layers ) , wherein the second circuit layer and each of the first circuit layers are respectively located in different heights ( Lee teaches these as separate layers, thus they must have different heights as measured in whatever direction they were formed ) ; a plurality of conductive vias ( [0025]: “ a plurality of wiring via layers ” ) connecting the first circuit layers with the second circuit layer ( [0025]: “ electrically connecting the plurality of wiring layers to one another ” ) ; and a plurality of interposer conductive pillars ( 110 ) , wherein one of the interposer conductive pillars is connected with one of the first circuit layers ( at least indirectly connected ) , and another of the interposer conductive pillars is connected with another of the first circuit layers ( at least indirectly connected ) . Modifying the semiconductor device of Oh by including the interposer module of Lee would arrive at the claimed device configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation, pillars and chips are connected to a substate in the same spatial orientation (Oh: Fig. 22: pillars 50 and chips 3; Lee: Fig. 1: pillars 110 and chips 420/320/220) . Lee provides a teaching to motivate one of ordinary skill in the art before the effective filing date to include the interposer module in that it would increase strength of the device ([0026]: “may improve stiffness of the semiconductor package”) . Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed interposer module because it would increase strength of the device. MPEP 2143 (I)(G). Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Oh as applied to claim 13 above, and further in view of Lee . Regarding claim 14, Oh discloses the semiconductor device according to claim 13 ( Fig. 22 ) , but fails to teach it “further com prising: an interposer module , comprising: a second substrate; and a plurality of interposer conductive pillars formed on the second substrate, wherein each interposer conductive pillar has an end surface, and the end surfaces of the interposer conductive pillars are different in height; wherein one of the interposer conductive pillars is connected to one of the first substrate, the first chip and the second chip, and another of the interposer conductive pillars is connected to another of the first substrate, the first chip and the second chip ” . Lee discloses a semiconductor device ( Fig. 1 ) , further comprising: an interposer module (101) , comprising: a second substrate ([0024]: “a core material”) ; and a plurality of interposer conductive pillars (110) formed on the second substrate, wherein each interposer conductive pillar has an end surface ( See annotated figure) , and the end surfaces of the interposer conductive pillars are different in height (different in the vertical direction) ; wherein one of the interposer conductive pillars is connected to one of the first substrate (connected to first substrate 550, See “end surfaces” in annotated figure) , the first chip and the second chip, and another of the interposer conductive pillars is connected to another of the first substrate, the first chip and the second chip (connected to second chip 320, See “end surfaces” in annotated figure) . Modifying the semiconductor device of Oh by including the interposer module of Lee would arrive at the claimed device configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation, pillars and chips are connected to a substate in the same spatial orientation (Oh: Fig. 22: pillars 50 and chips 3; Lee: Fig. 1: pillars 110 and chips 420/320/220) . Lee provides a teaching to motivate one of ordinary skill in the art before the effective filing date to include the interposer module in that it would increase strength of the device ([0026]: “may improve stiffness of the semiconductor package”) . Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed interposer module because it would increase strength of the device. MPEP 2143 (I)(G). Claim s 16 and 18- 20 are rejected under 35 U.S.C. 103 as being unpatentable over Oh in view of Lee . Regarding independent claim 16, Oh discloses a semiconductor device (Fig. 22) , comprising: a first substrate (1) ; a chip module (a collection of chips 3) disposed on the first substrate and having a plurality of upper surfaces ( See annotated figure) , wherein the surfaces of the chip module are different in height (different D1 heights are shown) ; an interposer module, comprising: a second substrate; and a plurality of interposer conductive pillars formed on the second substrate, wherein each interposer conductive pillar has an end surface, and the end surfaces of the interposer conductive pillars are different in height; wherein a first one of the interposer conductive pillars is connected to the first substrate, and a second one of the interposer conductive pillars is connected to one of the upper surfaces of the chip module; wherein the chip module comprises: a first chip ( 3, See annotated figure ) disposed on the first substrate and having a first lateral surface ( See annotated figure ) ; a second chip ( 3, See annotated figure ) disposed on the first chip, comprising a first protrusion ( See annotated figure ) protruding with respect to the first lateral surface ( protruding in the D2 direction ) and having a second lateral surface ( See annotated figure ) ; and a third chip ( 3, See annotated figure ) disposed on the second chip and comprising a second protrusion ( See annotated figure ) protruding with respect to the second lateral surface ( protruding in the D2 direction ) ; wherein the semiconductor device further comprises: a first substrate conductive pillar ( 51´ ) connecting the first protrusion with the first substrate ( electrically connecting ) ; a second substrate conductive pillar ( 52´ ) connecting the second protrusion with the first substrate ( electrically connecting ) ; and a single molding compound ( 7 ) encapsulating the first substrate ( encapsulating the D1 surface ) , the second chip ( fully encapsulating ) , the third chip ( fully encapsulating ) , the first substrate conductive pillar ( fully encapsulating ) , the second substrate conductive pillar ( fully encapsulating ) and the interposer module ; wherein a prominent part of the first chip protrudes with respect to a side of the second chip ( protrudes in the opposite D2 direction ) , and the second one of the interposer conductive pillars is connected to the prominent part ; wherein the second substrate conductive pillar is a single pillar ( the pillar is shown as a single piece ) which continuously extends to the first substrate from the third chip ( there are no interruptions in the pillar, thus it “continuously extends” ) . Oh teaches a chip module, substrate conductive pillars, and a single molding compound, but fails to teach including an interposer module. Thus, Oh fails to teach “ an interposer module , comprising: a second substrate ; and a plurality of interposer conductive pillars formed on the second substrate, wherein each interposer conductive pillar has an end surface , and the end surfaces of the interposer conductive pillars are different in height ; wherein a first one of the interposer conductive pillars is connected to the first substrate, and a second one of the interposer conductive pillars is connected to one of the upper surfaces of the chip module; wherein the chip module comprises: a first chip disposed on the first substrate and having a first lateral surface; a second chip disposed on the first chip, comprising a first protrusion protruding with respect to the first lateral surface and having a second lateral surface; and a third chip disposed on the second chip and comprising a second protrusion protruding with respect to the second lateral surface; wherein the semiconductor device further comprises: a first substrate conductive pillar connecting the first protrusion with the first substrate; a second substrate conductive pillar connecting the second protrusion with the first substrate; and a single molding compound encapsulating the first substrate, the second chip, the third chip, the first substrate conductive pillar, the second substrate conductive pillar and the interposer module ; wherein a prominent part of the first chip protrudes with respect to a side of the second chip, and the second one of the interposer conductive pillars is connected to the prominent part ” .

Modifying the semiconductor device of Oh by including the interposer module of Lee would arrive at the claimed device configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation, pillars and chips are connected to a substate in the same spatial orientation (Oh: Fig. 22: pillars 50 and chips 3; Lee: Fig. 1: pillars 110 and chips 420/320/220) . Lee provides a teaching to motivate one of ordinary skill in the art before the effective filing date to include the interposer module in that it would increase strength of the device ([0026]: “may improve stiffness of the semiconductor package”) . Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed interposer module because it would increase strength of the device.

Accordingly, claim 17 (and its dependent claims) should be allowed for the same reasons as claim 1 ” . Remarks at pg. 14 Examiner’s reply: Applicant’s arguments with respect to claim (s) 16 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant’s amendments change the scope of the claims, thus necessitating the new grounds of rejection raised in the instant Office action. Conclusion THIS ACTION IS MADE FINAL. 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.
