Abstract
A semiconductor device includes a first chip and a second chip. Active elements such as transistors are fabricated on the surface of the semiconductor substrate of the first chip. Passive elements such as inductors and capacitors are fabricated on the second chip. The first chip is so disposed on the second chip that the reverse surface of the first chip makes a contact onto the surface of the second chip. The active element and the passive element are electrically connected by bonding wire.
