Patent ID: 8269336

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes first and second openings; a heat spreader that includes a thermal post and a base, wherein the thermal post is adjacent to and integral with the base and extends above the base in an upward direction, and the base extends below the thermal post in a downward direction opposite the upward direction, covers the thermal post in the downward direction and extends laterally from the thermal post in lateral directions orthogonal to the upward and downward directions; and a conductive trace that includes a pad, a terminal and a signal post, wherein the signal post extends below the pad and above the terminal and an electrically conductive path between the pad and the terminal includes the signal post; wherein the semiconductor device is mounted on the heat spreader, overlaps the thermal post, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the thermal post and thereby thermally connected to the base; wherein the adhesive is mounted on and extends above the base, contacts the posts, the base and the terminal and extends laterally from the thermal post to or beyond the terminal; wherein the pad extends above the posts and the adhesive and the terminal extends below the posts; and wherein the thermal post extends into the first opening, the signal post extends into the second opening, the posts have the same thickness and are coplanar with one another between top and bottom surfaces of the pad and are the same metallic material as one another, and the base and the terminal have the same thickness and are coplanar with one another below the posts and are the same metallic material as one another.
