Patent ID: 8310043

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a post, a base, an ESD protection layer and an underlayer wherein (i) the post is adjacent to the base and extends above the base in an upward direction, (ii) the base covers 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 direction, (iii) the ESD protection layer is a thermally conductive, electrically insulative material that contacts and is sandwiched between and thermally connects and electrically isolates the base and the underlayer, extends below the base, covers the post in the downward direction and extends laterally beyond the post, and (iv) the underlayer extends below the ESD protection layer, covers the post in the downward direction and extends laterally beyond the post and wherein the heat spreader includes a cap that extends above and is adjacent to and covers in the upward direction and extends laterally from a top of the post and that contacts and overlaps the adhesive; and a conductive trace that includes a pad and a terminal; wherein the semiconductor device overlaps the post, the base, the ESD protection lay and the underlayer, is electrically connected to the pad and thereby electrically connected to the terminal, is electrically isolated from the underlayer and is thermally connected to the post and thereby thermally connected to the underlayer and wherein the pad and the cap have the same thickness where closest to one another and are coplanar with one another; wherein the adhesive is mounted on and extends above the base, 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 underlayer extends below the semiconductor device and the pad.
