Patent ID: 8314438

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a bump, a base and a flange, wherein (i) the bump is adjacent to the base and the flange, is integral with the flange, extends from the base in a first vertical direction and extends from the flange in a second vertical direction opposite the first vertical direction, (ii) the base extends from and covers the bump in the second vertical direction and extends laterally from the bump in lateral directions orthogonal to the vertical directions, (iii) the flange extends laterally from the bump and is spaced from the base, and (iv) a cavity in the bump faces in the first vertical direction, is covered by the bump in the second vertical direction, is spaced from the base by the bump and has an entrance at the flange; a substrate that includes a dielectric layer, wherein an aperture extends through the substrate; and a conductive trace that includes a pad and a terminal; wherein the semiconductor device extends into the cavity, is electrically connected to the pad and thereby electrically connected to the terminal, and is thermally connected to the bump and thereby thermally connected to the base; wherein the adhesive contacts the bump, the base, the flange and the dielectric layer, is sandwiched between the bump and the dielectric layer, between the flange and the dielectric layer and between the base and the flange, extends laterally from the bump to or beyond the terminal and extends to peripheral edges of the assembly; wherein the conductive trace is located outside the cavity; wherein the bump extends into the opening and the aperture and covers the semiconductor device in the second vertical direction; and wherein the cavity extends into the opening and the aperture.
