ABSTRACT:
A chip-on-chip-structure semiconductor device for a radio communication device, having a base band chip and a high-frequency chip piled up on and bonded to the surface thereof. The base band chip has a low-frequency signal processing unit for processing a signal in a first frequency band. The high-frequency chip has a high-frequency signal processing unit for processing a signal in a second frequency band of which frequency is higher than that of the first frequency band.
