Abstract:
A compact semiconductor device with an isolator. The semiconductor device includes two chips, namely a first semiconductor chip and a second semiconductor chip which are stacked with the main surfaces of the semiconductor chips partially facing each other. A first coil and a second coil which are formed in the first semiconductor chip and the second semiconductor chip respectively are arranged to face each other so as to be magnetically coupled during operation of the semiconductor device. The pair of first and second coils make up an isolator. The first coil is arranged in a manner to overlap part of the circuit region of the first semiconductor chip in plan view and the second coil is arranged in a manner to overlap part of the circuit region of the second semiconductor chip in plan view.

Claim (Index 9):
A semiconductor device comprising:\n a semiconductor substrate having a fifth surface and a sixth surface opposite to the fifth surface; a multilayer wiring layer provided over the fifth surface of the semiconductor substrate; a third coil provided in the multilayer wiring layer; a fourth coil provided in the multilayer wiring layer, facing the third coil, and magnetically coupled to the third coil; and a second insulating film interposed between the third coil and the fourth coil, wherein the third coil is located in a wiring layer lower than the fourth coil, and wherein the third coil and the fourth coil are arranged in a manner to overlap part of a circuit region provided in the fifth surface of the semiconductor substrate in plan view.
