Abstract
A semiconductor device includes a protected element and a connection section. The protected element is configured including a diode having an anode region and a cathode region. The diode is arranged on an active layer of a substrate including the active layer formed over a conductive substrate-support with an insulation layer interposed therebetween. The connection section electrically connects the cathode region of the protected element to the substrate-support.
Claims7
A semiconductor device comprising:
- a protected element that is configured to include a p-n junction diode between an anode region and a cathode region, and arranged on an active layer of a substrate including the active layer formed over a conductive substrate-support with an insulation layer interposed between the active layer and the substrate-support;
- a connection section that electrically connects the cathode region to the substrate-support;
- and
- a semiconductor element that is arranged in the active layer in a separate region to the protected element, the semiconductor element being any one out of an insulated-gate field-effect transistor, a bipolar transistor, a diffusion resistor, or a metal-insulator-semiconductor capacitor.
