Patent ID: 8067784

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; a substrate that includes a pad and a dielectric layer, wherein an aperture extends through the substrate; and a terminal; wherein the semiconductor device is mounted on the heat spreader, 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, extends into a gap in the aperture between the post and the substrate, extends across the dielectric layer in the gap, extends laterally from the post to or beyond the terminal and is sandwiched between the post and the dielectric layer and between the base and the substrate; wherein the substrate is mounted on the adhesive and extends above the base; and wherein the post extends into the opening and the aperture and is coplanar with the adhesive above the dielectric layer, and the base extends below the semiconductor device, the adhesive and the substrate.
