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; providing a conductive trace that includes a pad, a terminal and a selected portion of the conductive layer; etching the post, thereby forming a cavity in the post that faces in the upward direction; then mounting a semiconductor device on the post, wherein a heat spreader includes the post and the base and the semiconductor device extends into the cavity; 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.
