Patentability shall not be negated by the manner in which the invention was made. 07-21-aia AIA Claim s 1-2 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over US 2022/0415808 to Chava et al. (hereinafter Chava) in view of Wu et al. (US Patent No. 9,812,381, hereinafter Wu) . With respect to claim 1, Chava discloses a semiconductor package (300) (Chava, Fig. 4, ¶0023-¶0048), comprising: a redistribution layer structure (e.g., interconnect 122 of the substrate 102) (Chava, Fig. 4, ¶0024, ¶0045); a first semiconductor stack structure (e.g., 351/353) (Chava, Fig. 4, ¶0041, ¶0043-¶0045, ¶0049) on an upper surface (e.g., an upper surface of the substrate 102 including the interconnect 122) of the redistribution layer structure (122), wherein the first semiconductor stack structure comprises a first chiplet (e.g., 353) and a second chiplet (e.g., 351) disposed on the first chiplet (353); a second semiconductor stack structure (371/373) (Chava, Fig. 4, ¶0042-¶0046) on an upper surface (e.g., an upper surface of the substrate 102 including the interconnect 122) of the redistribution layer structure and side by side with the first semiconductor stack structure (351/353); a bridge die (e.g., bridge die 110 including bridge interconnect 112) (Chava, Fig. 4, ¶0027, ¶0043) forming an electrical connection between the first semiconductor stack structure (351/353) and the second semiconductor stack structure (371/373), the bridge die (110) being disposed above the first semiconductor stack structure (351/353) and the second semiconductor stack structure (371/373).

It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the semiconductor package of Chava/Park/Wu/Elsherbini by forming a semiconductor package including a memory stack on the logic device as taught by Malladi, wherein the memory includes HBM memory to have the semiconductor package, wherein the second chiplet comprises a high-bandwidth memory (HBM), in order to provide a semiconductor circuit with increased performance and reduced energy consumption (Malladi, ¶0001-¶0002, ¶0019-¶0025) . 07-21-aia AIA Claim s 15-18 are rejected under 35 U.S.C. 103 as being unpatentable over US 2022/0415808 to Chava in view of Park (US 2022/0165722), Wu (US Patent No. 9,812,381), and Elsherbini (US 2020/03664600), as applied to claim 14, and further in view of Chen (US 2023/0335519) . Regarding claim 15, Chava in view of Park, Wu, and Elsherbini discloses the semiconductor package of claim 14. Further, Chava discloses the semiconductor package, wherein the second interconnection structure (125/127, solder interconnects or bumps) (Chava, Fig. 4, ¶0027, ¶0052) comprises a bump, but does not specifically disclose a micro-bump. However, Chen teaches forming a conductive connector (128) (Chen, Figs. 6-7, ¶0009, ¶0038-¶0042) including a micro-bump between the semiconductor chip (50B) and the underlying interconnect structure (121) for solder bonding, to provide a semiconductor package having improved device performance and reduced costs. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the semiconductor package of Chava/Park/Wu/Elsherbini by forming a semiconductor package by using solder bonding as taught by Chen to have the semiconductor package, wherein the second interconnection structure comprises a micro-bump, in order to provide a semiconductor package having improved device performance and reduced costs (Chen, ¶0009, ¶0038-¶0042). Regarding claims 16-18, Chava in view of Park, Wu, and Elsherbini discloses the semiconductor package of claim 14. Further, Chava does not specifically disclose that the second interconnection structure comprises: a first silicon insulation layer and a plurality of first bonding pads on an upper surface of the second chiplet and on an upper surface of the second semiconductor stack structure; and a second silicon insulation layer and a plurality of second bonding pads on a bottom surface of the bridge die (as claimed in claim 16), wherein each bonding pad of the plurality of first bonding pads is directly bonded to each second bonding pad of the plurality of second bonding pads (as claimed in claim 17); wherein the first silicon insulation layer is directly bonded to the second silicon insulation layer (as claimed in claim 18). However, Chen teaches forming a semiconductor package using mixed bond types, wherein the semiconductor chip (50A) (Chen, Figs. 6-7, ¶0009, ¶0028-¶0037) is bonded to the interface die (111) by direct bonding such that a first silicon insulation layer (120) (Chen, Figs. 6-7, ¶0031) and a plurality of first bonding pads (122) are formed on an upper surface of the die (111), and a second silicon insulation layer (68) (Chen, Figs. 6-7, ¶0017, ¶0035) and a plurality of second bonding pads (66) are formed on a bottom surface of the die (50A), wherein each bonding pad (122) of the plurality of first bonding pads is directly bonded to each second bonding pad (66) of the plurality of second bonding pads, and wherein the first silicon insulation layer (120) (Chen, Figs. 6-7, ¶0031, ¶0034-¶0037) is directly bonded (e.g., oxide-to-oxide bond) to the second silicon insulation layer (68), to provide high density die-to-die interconnections having smaller pitch connections and reduced defects to improve device performance. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the semiconductor package of Chava/Park/Wu/Elsherbini by forming a semiconductor package using direct bonding between the dies as taught by Chen to have the semiconductor package, wherein the second interconnection structure comprises: a first silicon insulation layer and a plurality of first bonding pads on an upper surface of the second chiplet and on an upper surface of the second semiconductor stack structure; and a second silicon insulation layer and a plurality of second bonding pads on a bottom surface of the bridge die (as claimed in claim 16), wherein each bonding pad of the plurality of first bonding pads is directly bonded to each second bonding pad of the plurality of second bonding pads (as claimed in claim 17); wherein the first silicon insulation layer is directly bonded to the second silicon insulation layer (as claimed in claim 18), in order to provide high density die-to-die interconnections having smaller pitch connections and reduced defects to improve device performance (Chen, ¶0009, ¶0034-¶0037) . 07-21-aia AIA Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over US 2022/0415808 to Chava in view of Wu (US Patent No. 9,812,381) as applied to claim 19, and further in view of Chen (US 2023/0335519) . Regarding claim 20, Chava in view of Wu discloses the method of claim 19. Further, Chava does not specifically disclose the method, wherein: the bridge die is mounted on the first semiconductor stack structure and on the second semiconductor stack structure by hybrid bonding. However, Chen teaches forming a semiconductor package, wherein the circuit die (50A) is bonded to backside interconnect by hybrid bonding (Chen, Figs. 6-7, ¶0009, ¶0033-¶0037) including oxide-to-oxide bond and metal-to-metal bonding, to provide a semiconductor package having improved device performance. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify the method of Chava/Wu by forming a semiconductor package by using oxide-to-oxide bond and metal-to-metal bond as taught by Chen to have the method, wherein: the bridge die is mounted on the first semiconductor stack structure and on the second semiconductor stack structure by hybrid bonding, in order to provide a high density die-to-die interconnections having smaller pitch connections and reduced defects to improve device performance (Chen, ¶0009, ¶0034-¶0037).
