Abstract:
1. A method of making a semiconductor chip assembly, comprising: providing a bump, a ledge, an adhesive and a conductive layer, wherein flowing the adhesive in the first vertical direction into a gap located in the aperture between the bump 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; then mounting a semiconductor device on the bump, wherein a heat spreader includes the bump and a base, the bump is adjacent to the base and extends vertically from the base in the first vertical direction, the base includes a portion of the ledge that is adjacent to and integral with and extends laterally from the bump and the semiconductor device extends beyond the bump in the first vertical direction, is located outside the cavity and extends laterally within a periphery of 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 bump, thereby thermally connecting the semiconductor device to the base, wherein providing the base includes removing selected portions of the ledge after solidifying the adhesive.
