Patent ID: 8288792

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; a first adhesive that includes a first opening; a second adhesive that includes a second opening; a heat spreader that includes a first post, a second post and a base, wherein (i) the first post is adjacent to the base and extends vertically from the base in a first vertical direction, (ii) the second post is adjacent to the base and extends vertically from the base in a second vertical direction opposite the first vertical direction and (iii) the base is sandwiched between the posts and extends laterally from the posts in lateral directions orthogonal to the vertical directions; and a conductive trace that includes a pad, a terminal and an electrical interconnect, wherein an electrically conductive path between the pad and the terminal includes the electrical interconnect; wherein the semiconductor device is mounted on the first post, extends vertically beyond the base in the first vertical direction, extends laterally within peripheries of the posts, is electrically connected to the pad and thereby electrically connected to the terminal and is thermally connected to the first post and thereby thermally connected to the second post; wherein the first adhesive extends vertically beyond the base in the first vertical direction, extends laterally from the first post to or beyond the terminal and is sandwiched between the base and the pad; wherein the second adhesive extends vertically beyond the base in the second vertical direction, extends laterally from the second post to or beyond the terminal and is sandwiched between the base and the terminal; wherein the pad extends vertically beyond the first post and the base in the first vertical direction, the terminal extends vertically beyond the second post and the base in the second vertical direction and the electrical interconnect extends through the adhesives and the base and is spaced from and electrically isolated from the base; and wherein the first post extends into the first opening and extends vertically beyond a lateral surface of the pad in the first vertical direction, the second post extends into the second opening and extends vertically beyond a lateral surface of the terminal in the second vertical direction and the base is sandwiched between the adhesives and covers the semiconductor device in the second vertical direction.
