Patent ID: 7867878

Claim:
A method, comprising: providing a plurality of semiconductor chips, each semiconductor chip having connection contacts on a main surface; embedding the plurality of semiconductors chips in a mold material leaving the main surfaces of the semiconductor chips exposed, wherein the semiconductor chips and mold material together form a a first substrate having a first surface formed by the main surfaces of the semiconductor chips and mold material coplanar therewith and having an opposing second surface, and wherein the connection contacts of the semiconductor chips form an array of first connection elements on the first surface of the first substrate; providing a second substrate having a first surface and an opposing second surface, the second substrate comprising an array of second connection elements on the first surface of the second substrate; attaching the first connection elements on the first surface of the first substrate to the second connection elements; thinning at least one of the first substrate and the second substrate after the attachment of the first connection elements to the second connection elements; attaching the main surfaces of the semiconductor chips to a carrier prior to embedding the plurality of semiconductor chips in the mold material; and releasing the semiconductor chips from the carrier after embedding the plurality of semiconductors chips in the mold material.
