DETAILED ACTION
Election/Restrictions
Applicant’s election without traverse of claims 1-16 in the reply filed on October 27, 2025 is acknowledged.
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 1-2, 7-9 and 16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Dhakal et al. (Dhakal, US 2021/0028123 A1)
Regarding claim 1, Dhakal shows a microelectronic assembly, comprising: a package substrate (substrate 130 in FIG. 1A) comprising a conductive trace (conductive line 118 in FIG. 1A and [0014]) in a dielectric material ( dielectric material 132), the conductive trace (conductive line 118 and [0014]) surrounded by a conductive structure ( conductive structure 108/113 in FIG. 1A and [0017]) coupled to a ground connection (ground connection VSS in FIG. 1A), the package substrate further comprising metallization layers ( metallization layers between dielectric layer 132 in FGI. 1A) alternating with dielectric layers of the dielectric material (dielectric layer 132); and an integrated circuit (IC) die ( chip 102) coupled to a surface of the package substrate (substrate 130), the IC die coupled to the conductive trace by a conductive pathway ([0014]) ,wherein: the dielectric layers and the metallization layers are parallel to the surface of the package substrate (substrate 130),the conductive trace comprises a trench via (via 118) in at least one dielectric layer (dielectric layer 132), and the conductive structure comprises grounded plates ( conductive plate 110/111) extending across a length and width of the package substrate in the metallization layers on either side of the conductive trace (conductive line 118).
Regarding claim 2, Dhakal shows a microelectronic assembly, comprising: a package substrate (substrate 130 in FIG. 1A) comprising, wherein the conductive structure (conductive structure 108/113 in FIG. 1A) further comprises grounded traces (conductive line 118) in the metallization layers between the grounded plates ( VSS/ 111 in FIG. 1A).
Regarding claim 7, Dhakal shows a microelectronic assembly, comprising: a package substrate (substrate 130 in FIG. 1A) comprising, wherein the conductive trace ( conductive line 118 in FIG. 1A) comprises a plurality of parallel metal plates ( plates 111/VSS) in adjacent metallization layers (metal layer 118) and trench vias in the dielectric layers between the adjacent metallization layers ( metal layer 118), the trench vias in continuous contact with adjacent metal plates along a length of the conductive trace (conductive line 118).
Regarding claim 8, Dhakal shows a microelectronic assembly, comprising: a package substrate (substrate 130 in FIG. 1A) comprising, wherein conductive trace (conductive line 118) is a first conductive trace, and the microelectronic assembly further comprises a second conductive trace ( conductive line 118 i.e. plurality of conductive line 118) parallel to and coplanar with the first conductive trace ( conductive line 118).
Regarding claim 9, Dhakal shows a package substrate, comprising: a first ground plate ( plate 111/VSS/110 in FIG. 1A) and a second ground plate (plates 11/VSS/110) coupled to a ground connection ( connection 113);a dielectric layer ( dielectric layer 132) between the first ground plate (plates 111/VSS/110) and the second ground plate (plates VSS/111/110); and a conductive trace comprising a trench via ( via 118) in the dielectric layer (dielectric layer 132), the trench via not in contact with the first ground plate (VSS/111/110) or the second ground plate (VSS/110/111),wherein: the dielectric layer comprises a dielectric material ( dielectric layer 132), and the trench via is parallel to the first ground plate and the second ground plate (VSS/110/111).
Regarding claim 16, Dhakal shows a package substrate, further comprising another conductive trace ( conductive line 118) parallel to and coplanar with the conductive trace (conductive line 118), wherein the another conductive trace is separated from the conductive trace by a trace spacing filled with the dielectric material (dielectric layer 132).
Allowable Subject Matter
Claims 3-6, 10-15 are 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.
