Abstract:
1. A method of making a semiconductor chip assembly, comprising: providing a post, a base, a conductive layer and a first adhesive, wherein providing a conductive trace that includes a pad, a terminal and a selected portion of the conductive layer; flowing a second adhesive into and downward in a gap that laterally surrounds and is adjacent to the post, thereby contacting the adhesives with one another; solidifying the second adhesive; then mounting a semiconductor device on a heat spreader that includes the post and the base, wherein the semiconductor device overlaps the post and the second adhesive overlaps the conductive trace and does not cover the post and the pad in the upward direction; 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.
