Patent ID: 8129742

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a post and a base, wherein the post is adjacent to the base and extends above the base in an upward direction, and the base extends below the post in a downward direction opposite the upward direction and extends laterally from the post in lateral directions orthogonal to the upward and downward directions; and a conductive trace that includes a pad, a terminal and a plated through-hole, wherein the plated through-hole extends below the pad and above the terminal and an electrically conductive path between the pad and the terminal includes the plated through-hole; wherein the semiconductor device overlaps the post, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the post and thereby thermally connected to the base; wherein the adhesive is mounted on and extends above the base, contacts the post, the base, the terminal and the plated through-hole, extends laterally from the post to or beyond the terminal and is sandwiched between the base and the pad; and wherein the post extends into the opening and the base and the terminal have the same thickness and are coplanar with one another.
