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(s) 10-15 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fujita (US 2020/0275558) in view of Kamgaing (US 2022/0406523).

Fujita and Kamgaing are analogous art because they both are directed to semiconductor device and one of ordinary skill in the art would have had a reasonable expectation of success to modify Fujita with the specified features of Kamgaing because they are from the same field of endeavor.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the structure disclosed in Fujita to have the capacitor being a trench capacitor, as taught by Kamgaing, for the purpose of providing deep trenches within the glass core to enhance capacitance density ([14], Kamgaing).

Fujita and Kamgaing are analogous art because they both are directed to semiconductor device and one of ordinary skill in the art would have had a reasonable expectation of success to modify Fujita with the specified features of Kamgaing because they are from the same field of endeavor.

Fujita and Kamgaing are analogous art because they both are directed to method for forming a semiconductor device and one of ordinary skill in the art would have had a reasonable expectation of success to modify Fujita with the specified features of Kamgaing because they are from the same field of endeavor.

Fujita and Duong are analogous art because they both are directed to method for forming a semiconductor device and one of ordinary skill in the art would have had a reasonable expectation of success to modify Fujita with the specified features of Duong because they are from the same field of endeavor.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the method disclosed in Fujita to have the providing a cavity in the glass substrate, the cavity spaced apart from the TGV, the first layer of metal, the dielectric layer, and the second layer of metal deposited within the cavity, as taught by Duong, for the purpose of increasing capacitance density within a package while reducing the overall footprint of a package ([15], Duong).
Allowable Subject Matter
Claim 4 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims because the prior art of record neither anticipates nor render obvious the limitations of the base claims 1, 3, and 4 that recite "a patch antenna on the second surface, the patch antenna electrically coupled to the semiconductor die via the TGV" in combination with other elements of the base claims 1, 3, and 4.
Claim 17 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims because the prior art of record neither anticipates nor render obvious the limitations of the base claims 16 and 17 that recite "positioning a patch antenna on the first surface of the glass substrate, the semiconductor die and the patch antenna electrically coupled via the TGV" in combination with other elements of the base claims 16 and 17.
