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 .
Election/Restrictions
Applicant's election with traverse of Species E in the reply filed on 1/27/2026 is acknowledged. The traversal is on the ground(s) that it should be no serious burden on the Examiner to examine all of the claims. This is not found persuasive because the species of patentably distinct species require a different field of search.
The requirement is still deemed proper and is therefore made FINAL.
Claims 3-7, 12, 13, 19, 22, 23, 27, 28, 30, 31, 35 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim.
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 applicant regards as his invention.
Claim 16 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.
Claim 16 recites the semiconductor package assembly as claimed in Claim 15, wherein the first semiconductor die comprises a fifth interface arranged adjacent to the third interface and closer to the first edge than the third interface.
The fifth interface adjacent to the third interface and closer to the first edge than the third interface is indefinite. Claim 16 is dependent on Claim 15, which is dependent on Claim 1. Claim 1, recites “a third interface arranged on a first edge of the first semiconductor die”. It is unclear and indefinite as to how a third interface can be arranged on the first edge yet the fifth interface is closer to the first edge than the third interface.
For the purpose of examination on the merits, Claim 16 interpreted to recite the semiconductor package assembly as claimed in Claim 15, wherein the first semiconductor die comprises a fifth interface arranged adjacent to the third interface.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-2, 8-11, 14-18, 20-21, 24-26, 29 and 32-34 are rejected under 35 U.S.C. 102(a1) as being anticipated by Liff(US20200098692A1).

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.
Claim 36 is rejected under 35 U.S.C. 103 as being unpatentable over Liff(US20200098692A1) and Choi(US20230215849A1).
With respect to Claim 36, Liff teaches the semiconductor package assembly as claimed in Claim 29, wherein the bottom semiconductor die comprises a trench capacitor embedded in the bottom semiconductor die (¶ [0030]) and
the memory package (Fig 7A; 114-2; ¶ [0061]).
Liff does not teach electrically connected.
Choi teaches capacitor electrically connected (Fig. 1A; 130; ¶ [0037]).
It would be obvious to one with ordinary skill in the art before the effective filing date to combine the invention of Liff, a semiconductor package with a capacitor included in the bottom die, and the invention of Choi, a semiconductor package with a deep trench capacitor embedded on a substrate and coupled to a semiconductor die. This combination would produce a semiconductor package with a trench capacitor embedded on the bottom die and in contact with a neighboring die which is the memory package of Liff(114-2). The trench capacitor provides a decoupling capacitance to shunt noise Choi(¶ [0037]).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure:
Yee(US20170062383A1); This refence teaches a semiconductor packaging method with two semiconductor dies placed over a substrate
Li(US20220271002A1); This refence teaches a semiconductor packaging method of a three die construction
