Abstract:
1. A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a post, a base and a flange, wherein the post is adjacent to the base and the flange, extends above the base in an upward direction and extends below the flange in a downward direction opposite the upward direction, the base extends below the post and extends laterally from the post in lateral directions orthogonal to the upward and downward directions, the flange extends above the post and extends laterally beyond the post and a cavity in the flange is located above the post and faces in the upward direction; and a conductive trace that includes a pad and a terminal; wherein the semiconductor device extends into the cavity, is above and overlaps the post, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the post and thereby thermally connected to the base; wherein the adhesive is mounted on and extends above the base, extends above the post and below the flange, extends laterally from the post to or beyond the terminal and is sandwiched between the base and the flange; wherein the conductive trace is located outside the cavity; and wherein the post extends into the opening, the flange extends upwardly from the post in the opening and extends laterally above and overlaps the adhesive, the cavity extends into the opening and the base extends below the semiconductor device and the pad.
