MULTICHIP MODULE WITH STIFFENING FRAME AND ASSOCIATED COVERS

摘要

A multichip module includes a carrier, a stiffening frame, a plurality of semiconductor chips, and a plurality of covers. The carrier has a top surface and a bottom surface configured to be electrically connected to a motherboard. The stiffening frame includes a plurality of openings that accept the plurality of semiconductor chips and may be attached to the top surface of the carrier with an adhesive that absorbs dimensional changes between the stiffening frame and the carrier. The semiconductor chips are concentrically arranged within the plurality of openings of the stiffening frame and the plurality of covers are attached to the stiffening frame so as to enclose the plurality of openings.
