Abstract:
1. A method of making a semiconductor chip assembly, comprising: providing a post, a base, an adhesive and a conductive layer, wherein flowing the adhesive into and upward in a gap located in the aperture between the post and the conductive layer; solidifying the adhesive; then providing a conductive trace that includes a pad, a terminal and a selected portion of the conductive layer; providing a heat spreader that includes the post and the base, wherein providing the heat spreader includes 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 includes the copper surface layer, excludes the aluminum core and faces in the upward direction; mounting a semiconductor device on the heat spreader, wherein the semiconductor device overlaps the post; 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.
