Patent ID: 8163603

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 and integral with 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 and above the post and onto a top surface of the post and moving the post upwards in the aperture while flowing the adhesive such that the post extends above the dielectric layer; solidifying the adhesive; then grinding the post, the adhesive and the conductive layer such that the post, the adhesive and the conductive layer are laterally aligned with one another at a top lateral surface that faces in the upward direction, thereby removing the adhesive from the top surface of the post; 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.
