Abstract:
1. A stacked microelectronic assembly comprising: a) a plurality of microelectronic subassemblies, each said subassembly comprising: i) a substrate having at least one attachment site, a plurality of first contacts and a plurality of second contacts; ii) at least one microelectronic element assembled to said at least one attachment site and electrically connected to at least some of said first and second contacts, said substrate being folded so that said first contacts are accessible at a bottom of said subassembly and said second contacts are accessible at a top of said subassembly b) said plurality of subassemblies being stacked one on top of another substantially vertically so that an upper subassembly of said plurality of subassemblies is adjacent a lower subassembly of said plurality of subassemblies, some of the first contacts of the upper subassembly being connected to at least some of the second contacts of the lower subassembly, wherein the substrate of at least one of said subassemblies comprises a plurality of attachment sites and a plurality of microelectronic elements assembled to said attachment sites, and wherein the substrate is folded so that at least some of said plurality of microelectronic elements overlie one another, said assembly further comprising an encapsulant at least partially surrounding at least one of said microelectronic elements.
