DETAILED ACTION
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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 3/23/2026 has been entered.
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.
Claims 1, 3-5, 7-14 and 16-20 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.
Claim 1 recites “a second cap layer covering and in contact with a top surface and a sidewall of the first cap layer and the first adjustment layer” in lines 8-9 (emphasis added).
The terms “a top surface” and “a sidewall” are recited in the singular, but are in reference to surfaces of two separate elements (first cap layer and first adjustment layer). It is unclear if the claim requires the second cap layer to contact a single top surface (a top surface of either the cap layer or the adjustment layer) and a single sidewall (a sidewall of either the cap layer or the adjustment layer), or if the second cap layer contacts two top surfaces (top surfaces of both the cap layer and the adjustment layer) and two sidewalls (sidewalls of both the cap layer and the adjustment layer). This renders the scope of claim 1 indefinite.
Claims 5 and 14 include language equivalent to the indefinite subject matter above.
Claims 3-4, 6-13 and 15-20 depend on claims 1, 5 and 14, and are rejected under 35 USC § 112(b) for implicitly including the indefinite subject matter above.
For the purpose of compact prosecution, the Examiner has interpreted claims 1, 5 and 14 to mean:
“…a second cap layer, covering and in contact with respective top surfaces and respective sidewalls of each of the first cap layer and the adjustment layer.”
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1 and 3-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Burke et al. (PG Pub. No. US 2010/0117195 A1).
Regarding claim 1, Burke teaches a semiconductor device (fig. 2F), comprising:
a substrate (¶ 0017: 102);
a bonding structure (¶ 0016: 118, including a bonding surface), located over the substrate (fig. 2F: 118 located over 102);
an adjustment layer (¶ 0018: 110/112), located on a bonding pad of the bonding structure (fig. 2F: 110/112 located on bottom pad-shaped surface of 118);
an interconnection structure (¶ 0016: 104), located between the substrate and the bonding structure (fig. 2F: 104 located between 102 and 118);
a first cap layer (¶ 0018: 108), covering a dielectric layer (¶ 0021: 124) and an entirety of a topmost surface of a topmost conductive layer (¶ 0017: 104a) of the interconnection structure (fig. 2F: 124 covers a portion of top surface of 124 and entirety of top surface of 104a); and
a second cap layer (¶ 0027: 114), covering and in contact with a top surface and a sidewall of the first cap layer and the adjustment layer (fig. 2F: 114 covers and in contact with top and side surfaces of 110/112 and 108).
Regarding claim 3, Burke teaches the semiconductor device according to claim 1, wherein the adjustment layer comprises a conductive layer, a semiconductor layer, an insulating layer or a combination thereof (¶ 0018: in at least one embodiment, adjustment layer portion 110 includes conductive material, and portion 112 comprises insulating dielectric).
Regarding claim 4, Burke teaches the semiconductor device according to claim 1, wherein the bonding pad, the first cap layer, the adjustment layer, the second cap layer and the topmost conductive layer form a passive device (¶ 0018: passive capacitor) or a dummy structure.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 5, 6-14 and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Burke in view of Chen et al. (PG Pub. No. US 2021/0265313 A1).
Regarding claim 5, Burke teaches a semiconductor device, comprising:
a first die (¶ 0017: 102), comprising a first interconnection structure (¶ 0016: 104);
a bonding structure (¶ 0016: 118, including a bonding surface);
a first adjustment layer (¶ 0018: composite structure including elements 110 and 112), located between a first bonding pad of the bonding structure and a first topmost conductive layer (¶ 0017: 104a) of the first interconnection structure (fig. 2F: 110/112 located between pad portion of 118 and 104a);
a first cap layer (¶ 0018: 108), covering a first dielectric layer (¶ 0021: 124) and an entirety of a topmost surface of the first topmost conductive layer of the first interconnection structure (fig. 2F: 108 covers a portion of 124 and entirety of a top surface of 104a); and
a second cap layer (¶ 0027: 114), covering and in contact with a top surface and a sidewall of the first cap layer and the first adjustment layer (fig. 2F: 114 covers and contacts top and sidewall surfaces of 108 and 110/112).
Burke does not teach the semiconductor device further comprising:
a second die, comprising a second interconnection structure;
the bonding structure, bonding the first die and the second die.
Chen teaches a semiconductor device (¶ 0012 & fig. 10) including:
a first die (¶ 0054: 100, similar to 102 of Burke) comprising a first interconnection structure (¶ 0056: 130, similar to 104 of Burke);
a second die (¶ 0054: 200), comprising a second interconnection structure (¶ 0048: 230), a bonding structure (¶ 0054: 170) bonding the first die and the second die (fig. 1L: 170 bonds 100 and 200).
It would have been obvious to one of ordinary skill in the art at the time the invention was filed to configure the semiconductor device of Burke with the second die of Chen, as a means to increase functionality and/or capacity of memory and/or logic in a single package (Chen, ¶¶ 0055, 0083 among others).
Regarding claim 7, Burke in view of Chen teaches the semiconductor device according to claim 5, wherein the first bonding pad, the first cap layer, the first adjustment layer, the second cap layer and the first topmost conductive layer form a first capacitor (Burke, ¶ 0024-0026: pad-shaped portion of 118, 108, 110/112, 114 and 104a form a capacitor structure), a first resistor or a first dummy structure.
Regarding claim 8, Burke in view of Chen teaches the semiconductor device according to claim 5, comprising a bonding structure (Chen, 170) and a second topmost conductive layer (Chen, ¶ 0030: 232) of a second interconnection structure (fig. 1: 230 includes topmost 232).
Burke in view of Chen as modified above fails to teach the semiconductor device further comprising:
a second adjustment layer, located between a second bonding pad of the bonding structure and a second topmost conductive layer of the second interconnection structure.
However, Chen does teach a second adjustment layer (Chen, ¶ 0031: 246), located between a second bonding pad (Chen, ¶ 0023: 272a) of the bonding structure (Chen, 170/270) and a second topmost conductive layer of a second interconnection structure (Chen, fig. 1L: 246 located between 272a and second conductive pad 232 of 230).

Furthermore, it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art. St Regis Paper Co. v. Bemis Co., 193 USPQ 8. In the instant case, the second adjustment layer, second bonding pad, and second topmost conductive layer are merely duplication of the essential working parts of Burke and Chen.
Regarding claim 9, Burke in view of Chen teaches the semiconductor device according to claim 8, comprising a second interconnection structure (Chen, e.g. second portion of 270) and a second adjustment layer (Chen, 244).

Furthermore, it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art. St Regis Paper Co. v. Bemis Co., 193 USPQ 8.

In the instant case, forming the second adjustment layer, second bonding pad, and second topmost conductive layer are merely duplication of the essential working parts of Burke and Chen.
Regarding claim 18, Burke in view of Chen teaches the method according to claim 17, comprising forming a second interconnection structure (Chen, e.g. second portion of 270) and a second adjustment layer (Chen, 244).
