Patent ID: 8148747

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a post, a base and a cap, wherein the post is adjacent to the base and extends above the base in an upward direction and thermally connects the base and the cap, 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 the cap extends above and is adjacent to and covers in the upward direction and extends laterally from a top of the post; and a conductive trace that includes a pad and a terminal; wherein the semiconductor device is mounted on the cap, overlaps the post, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the cap and thereby thermally connected to the base; wherein the adhesive is mounted on and extends above the base, extends into a gap between the post and the pad, extends laterally from the post to or beyond the terminal and is sandwiched between the base and the pad; wherein the pad is mounted on the adhesive and extends above the base; and wherein the post extends into the opening, the cap overlaps the adhesive, the cap is thinner than the pad where the cap is adjacent to the top of the post, the cap is above a bottom surface of the pad where the cap is adjacent to the top of the post, the cap is below a top surface of the pad where the cap is adjacent to the top of the post and the base extends below the semiconductor device, the adhesive and the pad.
