Abstract:
1. A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a base; and a conductive trace that includes a pad and a terminal; wherein a cavity extends through the adhesive in the opening into the base, faces in the upward direction, has a diameter that decreases as it extends downwardly in the base and is covered by the base in the downward direction; wherein the semiconductor device extends into the cavity and is covered by the cavity in the downward direction, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the base; wherein the adhesive is mounted on and contacts and extends above the base, extends between the cavity and the pad, extends laterally from the opening to or beyond the terminal and is sandwiched between the base and the pad; wherein the opening has a diameter that increases as it extends downwardly; wherein the conductive trace is located outside the cavity; and wherein the base extends below the semiconductor device and the pad.
