Patent ID: 7948076

Claim:
A semiconductor chip assembly, comprising: a semiconductor device; an adhesive that includes an opening; a heat spreader that includes a post and a base, wherein the post is adjacent to the base and extends above the base in an upward direction, and the base extends below the post in a downward direction opposite the upward direction and extends laterally from the post in lateral directions orthogonal to the upward and downward directions; a substrate that includes a pad, a routing line, a first via and a dielectric layer, wherein the pad extends above the dielectric layer, the routing line extends below the dielectric layer, the first via extends through the dielectric layer to the routing line, and an aperture extends through the substrate; a second via that extends through the adhesive to the routing line; and a terminal that extends below the adhesive; wherein an electrically conductive path between the pad and the terminal includes the first via, the routing line and the second via; wherein the semiconductor device is mounted on the heat spreader, overlaps or is overlapped by the post, is electrically connected to the pad and the terminal, and is thermally connected to the post and the base; wherein the adhesive is mounted on and extends above the base, extends into a gap in the aperture between the post and the substrate, extends across the dielectric layer in the gap and is sandwiched between the post and the dielectric layer and between the base and the substrate; wherein the substrate is mounted on the adhesive and extends above the base, and the routing line is embedded in the adhesive; and wherein the post extends through the opening into the aperture and above the dielectric layer, and the base extends below the adhesive and the substrate.
