Abstract:
1. A semiconductor device, comprising: a first substrate comprising a first device element formed on a front surface thereof; a second substrate comprising a second device element formed on a front surface thereof; a first pad electrode disposed on the front surface of the first substrate and electrically connected to the first device element; a second pad electrode disposed on the front surface of the second substrate and electrically connected to the second device element; and an adhesive layer disposed between the front surface of the first substrate and the front surface of the second substrate so that the first and second substrates are adhered together to form an integrated die, wherein, in plan view of the semiconductor device, the first pad electrode does not overlap any pad electrode formed on the front surface of the second substrate, and the second pad electrode does not overlap any pad electrode formed on the front surface of the first substrate.
