Abstract:
1. A method of making a semiconductor chip assembly, comprising: providing a thermal post, a signal post, a base, a terminal, an adhesive and a conductive layer, wherein flowing the adhesive into and upward in a first gap located in the first aperture between the thermal post and the conductive layer and in a second gap located in the second aperture between the signal post and the conductive layer; flowing the adhesive into and downward in a slot between the base and the terminal; solidifying the adhesive; providing a conductive trace that includes a pad, the terminal and the signal post, wherein the pad includes a selected portion of the conductive layer; mounting a semiconductor device on a heat spreader that includes the thermal post and the base, wherein the semiconductor device overlaps the thermal post; electrically connecting the semiconductor device to the pad, thereby electrically connecting the semiconductor device to the terminal, wherein an electrically conductive path between the pad and the terminal includes the signal post; and thermally connecting the semiconductor device to the thermal post, thereby thermally connecting the semiconductor device to the base.
