Abstract:
1. A multi-chip module comprising: a substrate; a first semiconductor device having an active surface including a central region encompassing a plurality of bond pads and a back side, the back side affixed to the substrate; a second semiconductor device, the second semiconductor device having an active surface including a central region encompassing a plurality of bond pads and a back side; at least two spacers interposed between the active surface of the first semiconductor device and the back side of the second semiconductor device and positioned at a peripheral edge of the first semiconductor device; a plurality of first discrete conductive elements extending between the plurality of bond pads of the first semiconductor device and to a contact area on a first side of the substrate, wherein each conductive element extending to the contact area on the first side of the substrate extends through a common aperture formed between the active surface of the first semiconductor device, the back side of the second semiconductor device, and two spacers of the at least two spacers positioned therebetween; and a plurality of second discrete conductive elements, extending to and between the plurality of bond pads of the second semiconductor device and the substrate.
