When responding to this office action, applicants are advised to provide the examiner with line numbers and page numbers in the application and/or references cited to assist the examiner in locating appropriate paragraphs. Per MPEP 2111 and 2111.01, the claims are given their broadest reasonable interpretation and the words of the claims are given their plain meaning consistent with the specification without importing claim limitations from the specification. For Examiner’s Interview fill out the online Automated Interview Request (AIR) form (http://www.uspto.gov/patent/uspto-automated-interview-request-air-form.html).

Claim Rejections - 35 USC § 103 07-20-aia AIA The following is a quotation of AIA 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. Claim(s) 8 and 17 is/are rejected under AIA 35 U.S.C. 103 as being unpatentable over Hwang et al., US PG pub. 20200135699 A1. Re: Claim 8, Hwang discloses all the limitations of claim 7 on which this claim depends. Hwang further discloses: wherein the second front insulating film/layer (120, fig. 4) region is directly bonded to the first gap filling portion (180 portion next to region 100A-100C, fig. 3). Hwang figure 4 is silent regarding: a bonding interface layer is formed between insulating layer and gap filling portion. Hwang figure 8 teaches a bonding interface layer (164D) between the gap filling portion (180 portion next to region 100A-100C, fig. 3) and front insulating layer (120). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include bonding layer between gap filling and insulating layer thereby increase the bonding strength between the chip layers. Re: Claim 17, Hwang discloses all the limitations of claim 16 on which this claim depends. Hwang further discloses: wherein the second front insulating film/layer (120, fig. 4) region is directly bonded to the first gap filling portion (180 portion next to region 100A-100C, fig. 3). Hwang figure 4 is silent regarding: a bonding interface layer is formed between insulating layer and gap filling portion. Hwang figure 8 teaches a bonding interface layer (164D) between the gap filling portion (180 portion next to region 100A-100C, fig. 3) and front insulating layer (120). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include bonding layer between gap filling and insulating layer thereby increase the bonding strength between the chip layers. Claim(s) 9 and 18 is/are rejected under AIA 35 U.S.C. 103 as being unpatentable over Hwang et al., US PG pub. 20200135699 A1; in view of Sun et al., US PG pub. 20230361068 A1. Re: Claim 9, Hwang discloses all the limitations of claim 8 on which this claim depends. Hwang is silent regarding: wherein the bonding interface layer (164D, fig. 8) has a thickness in a range of 2 Å to 500 Å. Sun teaches the bonding interface layer 104 between gap filling layer 102 and insulating layer 92 as shown in figure 9-10 (¶0048). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include bonding layer that has a small thickness for example about 30 Å to about 200 Å since this can miniaturize the device. Re: Claim 18, Hwang discloses all the limitations of claim 17 on which this claim depends. Hwang is silent regarding: wherein the bonding interface layer has a thickness in a range of 2 Å to 500 Å. Sun teaches the bonding interface layer 104 between gap filling layer 102 and insulating layer 92 as shown in figure 9-10 (¶0048). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include bonding layer that has a small thickness for example about 30 Å to about 200 Å since this can miniaturize the device. Claim(s) 19 is/are rejected under AIA 35 U.S.C. 103 as being unpatentable over Hwang et al., US PG pub. 20200135699 A1; in view of Jee et al., US PG pub. 20230074933 A1. Re: Claim 19, Hwang discloses all the limitations of claim 11 on which this claim depends. Hwang is silent regarding: wherein a thickness of the top core die (110D, fig. 3) is in a range of 100 μm to 300 μm, and a thickness of each of the intermediate core dies (100A,100B,100C, fig. 3) is in a range of 20 μm to 50 μm. Jee discloses a thickness of top core die (200H and 400, fig. 1A) can be in a range of 100 μm to 300 μm (H2 and H3 thickness ¶0038 and ¶0049), and a thickness of each of the intermediate core dies (200, fig. 1A) is in a range of 20 μm to 50 μm (¶0038). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to include a thicker top core die than each of the intermediate core dies since the thicker thickness of the top core die can protect any external damage from the inner intermediate core dies. * Prior art made of record and not relied upon are considered pertinent to current application disclosure. *(“Suh et al., US Patent 11508685 B2”) discloses a semiconductor package includes a substrate, a first semiconductor chip disposed on the substrate, and a second semiconductor chip disposed on a top surface of the first semiconductor chip. The first semiconductor chip includes a conductive pattern disposed on the top surface of the first semiconductor chip and a first protective layer covering the top surface of the first semiconductor chip and at least partially surrounds the conductive pattern. The second semiconductor chip includes a first pad that contacts a first through electrode on a bottom surface of the second semiconductor chip. A second protective layer surrounds the first pad and covers the bottom surface of the second semiconductor chip. A third protection layer fills a first recess defined in the second protective layer to face the inside of the second protective layer. The first protective layer and the third protective layer contact each other. *(“Yoshida et al., US PG pub. 20110147945 A1”) discloses a semiconductor device includes a chip stacked body where a plurality of semiconductor chips are stacked, and penetration electrodes respectively formed in the semiconductor chips are electrically interconnected in stacking order of the semiconductor chips, a first support member that is disposed to face a first semiconductor chip formed in one end of the chip stacked body, and including electrodes electrically connected to the penetration electrodes of the first semiconductor chip, and a wiring board that is disposed to face a second semiconductor chip formed in an end opposed to the one end of the chip stacked body, and including external electrodes on a surface opposed to a surface facing the second semiconductor chip that is to be electrically connected to the penetration electrodes of the second semiconductor chip. *(“Min et al., US PG pub. 20150048493 A1”) discloses a semiconductor package includes a circuit substrate, a plurality of semiconductor chips stacked on the circuit substrate, insulating adhesive patterns interposed between the semiconductor chips, a heat slug provided on an uppermost semiconductor chip and adhered to the uppermost semiconductor chip by a heat dissipative adhesive pattern, and a mold structure provided on the circuit substrate to cover sidewalls of the semiconductor chips, the insulating adhesive patterns, the heat dissipative adhesive pattern and the heat slug. A failure of the semiconductor package during a manufacturing process of the mold structure may be reduced. The semiconductor package may therefore have good operating characteristics and reliability.
