Abstract:
A multi-chip module assembly comprising:(a) a substrate having a conductive surface facing in a first direction,(b) a first integrated circuit (IC) layer having a conductive surface facing in a second direction opposite to said first direction, towards said conductive surface of said substrate, said conductive surface of said first IC layer being electrically connected to said conductive surface of said substrate,(c) a second IC layer positioned over said first IC layer, said second IC layer having a conductive surface facing in said first direction, and(d) a third IC layer having a conductive surface facing in said second direction, said third IC layer being positioned at least in part over the second IC layer, the conductive surface of said third IC layer being electrically connected to said conductive surface of said second IC layer, wherein said conductive surface of said third IC layer is directly electrically connected to said conductive surface of said substrate.
