Patent ID: 7675151

Claim:
An electronic device, comprising: a first silicon-based circuit carrying substrate; a second silicon-based circuit carrying substrate, the second silicon-based circuit carrying substrate being closely coupled to the first silicon-based circuit carrying substrate by a solder connection between the first silicon-based circuit carrying substrate and the second silicon-based circuit carrying substrate, the solder connection electrically connecting the first silicon-based circuit carrying substrate and the second silicon-based circuit carrying substrate; a plurality of dies connected to a first face of the first silicon-based circuit carrying substrate, the plurality of dies comprising a first die and a second die; and a third die connected to a first face of the second silicon-based circuit carrying substrate, wherein the dies are completely enclosed in a cavity defined by the first face of the first silicon-based circuit carrying substrate, the first face of the second silicon-based circuit carrying substrate, sides of the first silicon-based circuit carrying substrate and sides of the second silicon-based circuit carrying substrate, wherein a second face of the first silicon-based circuit carrying substrate is opposite the first face of the first silicon-based circuit carrying substrate and includes solder connections, wherein additional dies are not connected to the second face of the first silicon-based circuit carrying substrate.
