Patent ID: 7787225

Claim:
A semiconductor apparatus comprising: an electroconductive member; a switching device electrically connected to the electroconductive member on the electroconductive member and having a withstand voltage between a front side and a back side as a first withstand voltage; a back-side high-withstand-voltage integrated circuit provided on the electroconductive member separately from the switching device, incorporating a control circuit for controlling turning-on/off of the switching device, and having a withstand voltage between a front side and a back side as a second withstand voltage higher than the first withstand voltage; an insulating substrate provided on the electroconductive member separately from the switching device and the back-side high-withstand-voltage integrated circuit; input/output wiring connected to the insulating substrate; first wiring connecting the insulating substrate and the switching device; and second wiring connecting the insulating substrate and back-side high-withstand-voltage integrated circuit.
