Abstract:
1. An electronic system, comprising: a first integrated-circuit chip having an electrical connection front side and a back side; a second integrated-circuit chip; a first substrate wafer which extends between the first and second integrated-circuit chips, said electrical connection front side of the first integrated-circuit chip being mounted to a surface of said first substrate wafer; a second substrate wafer placed facing the back side of the first integrated-circuit chip; a layer of thermally conductive adhesive interposed between the back side of first integrated-circuit chip and a surface of the second substrate wafer; and wherein the first integrated-circuit chip and the first substrate wafer form a first electronic device including a first electrical connection network within the first substrate wafer, and wherein the second integrated-circuit chip and a third substrate wafer form a second electronic device including a second electrical connection network within the third substrate wafer.
