Abstract:
1. A method of making a semiconductor chip assembly, comprising: providing a post, a base, an adhesive and a substrate, wherein 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.
