Patent ID: 7312518

Claim:
A miniaturized multi-chip module adapted to be mounted on a circuit board so as to establish electrical connection therewith, said miniaturized multi-chip module comprising: a substrate having a first surface, a second surface opposite to said first surface, a plurality of first solder pads formed on said second surface, and a plurality of second solder pads formed on said second surface and connected electrically to said first solder pads; a plurality of integrated circuit chips, at least one of which is mounted on said second surface of said substrate at corresponding ones of said first solder pads, said at least one of said integrated circuit chips having a largest height measured from said second surface of said substrate; and an interposer having a thickness not less than the largest height of said at least one of said integrated circuit chips on said second surface of said substrate, said interposer including a substrate-confronting surface, a board-confronting surface opposite to said substrate-confronting surface, a surrounding wall surface interconnecting said substrate-confronting surface and said board-confronting surface, and a plurality of conductors that extend between said substrate-confronting surface and said board-confronting surface, said substrate-confronting surface being mounted on said second surface of said substrate such that said conductors are connected electrically and respectively to said second solder pads, and such that said surrounding wall surface cooperates with said second surface of said substrate to form a receiving space that receives said at least one of said integrated circuit chips on said second surface of said substrate therein, said board-confronting surface being adapted for mounting on the circuit board such that said conductors are connected electrically to the circuit board.
