Integrated circuit (IC) device with multi-die integration

Abstract:

A method for manufacturing an integrated circuit (IC) device. A first IC wafer is diced to obtain a first superdie including a plurality of first die. A second IC wafer is diced to obtain a second superdie including a plurality of second die. The first superdie and the second superdie are placed on an interposer substrate to form at least part of a composite IC wafer, wherein each of the first die is aligned with a respective one of the second die in the composite IC wafer. The composite IC wafer is diced to obtain a plurality of IC devices, where each of the IC devices includes a respective one of the first die and the second die with which it is aligned.
