Edge connect wafer level stacking
First Claim
1. A stacked microelectronic assembly, comprising:
- a first stacked subassembly and a second stacked subassembly overlying a portion of the first stacked subassembly, each stacked subassembly including at least a respective first microelectronic element having a face and a respective second microelectronic element having a face overlying and parallel to a face of the first microelectronic element, each of the first and second microelectronic elements having edges extending away from the respective faces, each of the first and second stacked subassemblies having a land exposed at a face of the subassembly and a lead, the lead coupled to the land and extending along the face of the subassembly and from the face of the subassembly continuously about the edges of the first and second microelectronic elements thereof; and
a bond wire conductively connecting the land of the first stacked subassembly with the land of the second stacked subassembly.

Abstract
A stacked microelectronic assembly includes a first stacked subassembly and a second stacked subassembly overlying a portion of the first stacked subassembly. Each stacked subassembly includes at least a respective first microelectronic element having a face and a respective second microelectronic element having a face overlying and parallel to a face of the first microelectronic element. Each of the first and second microelectronic elements has edges extending away from the respective face. A plurality of traces at the respective face extend about at least one respective edge. Each of the first and second stacked subassemblies includes contacts connected to at least some of the plurality of traces. Bond wires conductively connect the contacts of the first stacked subassembly with the contacts of the second stacked subassembly.
