Patent ID: 8324723

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a bump and a flange, wherein (i) the bump includes first, second and third bent corners with the second bent corner between the first and third bent corners, is adjacent to the flange at the first bent corner, is spaced from the flange at the second and third bent corners, is integral with the flange and extends from the flange in a second vertical direction opposite a first vertical direction, (ii) the flange extends laterally from the bump in lateral directions orthogonal to the vertical directions, and (iii) a cavity in the bump faces in the first vertical direction, is covered by the bump in the second vertical direction, is shaped by the first, second and third bent corners and has an entrance at the flange, a first angle between the first and second bent corners and a second angle between the second and third bent corners; and a conductive trace that includes a pad and a terminal; wherein the semiconductor device is located within the cavity, extends beyond the first bent corner in the second vertical direction but not the first vertical direction, extends beyond the second bent corner in the first and second vertical directions and extends beyond the third bent corner in the first vertical direction but not the second vertical direction, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the bump; wherein the adhesive contacts the bump and the flange and extends laterally from the bump to or beyond the terminal; wherein the conductive trace is located outside the cavity; wherein the bump extends into the opening, covers the semiconductor device in the second vertical direction and provides a recessed die paddle and a reflector for the semiconductor device; and wherein the cavity extends into the opening.
