Patent ID: 8067270

Claim:
A method of making a semiconductor chip assembly, comprising: providing a post, a base, an adhesive and a substrate, wherein the substrate includes a conductive layer and a dielectric layer, the post is adjacent to the base, extends above the base in an upward direction, extends through an opening in the adhesive and extends into an aperture in the substrate, 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, the adhesive is mounted on and extends above the base, is sandwiched between the base and the substrate and is non-solidified, the substrate is mounted on and extends above the adhesive, and the conductive layer extends above the dielectric layer, and a gap is located in the aperture between the post and the substrate; then flowing the adhesive into and upward in the gap, wherein flowing the adhesive includes forcing the adhesive above the post and the conductive layer; solidifying the adhesive; then mounting a semiconductor device on a heat spreader that includes the post and the base, wherein the semiconductor device overlaps the post, a conductive trace includes a pad, a terminal and a selected portion of the conductive layer and the pad is electrically connected to the terminal; electrically connecting the semiconductor device to the pad, thereby electrically connecting the semiconductor device to the terminal; and thermally connecting the semiconductor device to the post, thereby thermally connecting the semiconductor device to the base.
