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.
Notes: when present, semicolon separated fields within the parenthesis (; ;) represent, for example, as (30A; Fig 2B; [0128]) = (element 30A; Figure No. 2B; Paragraph No. [0128]). For brevity, the texts “Element”, “Figure No.” and “Paragraph No.” shall be excluded, though; additional clarification notes may be added within each field. The number of fields may be fewer or more than three indicated above. These conventions are used throughout this document.
Claims 15 is rejected under 35 U.S.C. 103 as being unpatentable over Jeon in view of Lin et al. (US 20250015069 A1 - hereinafter Lin).
Regarding Claim 15, Jeon teaches claim 14 from which claim 15 depends. Jeon further teaches a conductive pad (140 – [0058]) on the upper pad (left 130). But Jeon does not expressly disclose wherein the conductive pad includes Ni and/or Au.
In a related art, Lin teaches a conductive pad is formed of gold and nickel (Lin – [0017] – “the conductive pad 53 may be or include Au, Ag, Cu, Ni, another metal, a solder alloy”).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the forming of a conductive pad of gold and/or nickel as taught by Lin into Jeon.
An ordinary artisan would have been motivated to integrate Lin structure into Jeon structure in the manner set forth above for, at least, for the obvious benefit of superior conductivity.
Allowable Subject Matter
Claims 2-3, 13, 16-17 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.
The following is the Examiner’s Reasons for Allowance:
The prior art fails to disclose and would not have rendered obvious:

Claim 3 depends from claim 2.
Regarding claim 13: The semiconductor package of claim 12, wherein the penetration connecting portion comprises: a first connecting portion; a second connecting portion on the first connecting portion; and a third connecting portion on the second connecting portion, wherein a width of an upper portion of the second connecting portion in the first direction is greater than a width of a lower portion of the second connecting portion in the first direction, wherein a width of the first connecting portion in the first direction is greater than the width of the lower portion of the second connecting portion in the first direction, and wherein an insulating material extends around the first connecting portion and the second connecting portion.
