Abstract
A protecting element, comprising a first n+-type region, an insulating region, and a second n+-type region, is connected in parallel between two terminals of an FET. Since discharge across the first and second n+ regions is enabled, electrostatic energy that reaches the operating region of the FET can be attenuated without increasing the parasitic capacitance.
