Abstract
A semiconductor device includes a semiconductor chip with a gate electrode, and a stress detecting element placed on a surface of the semiconductor chip, and which detects stress applied to the surface. The semiconductor device controls a control signal to be applied to the gate electrode in response to stress detected by the stress detecting element. The stress detecting element is preferably provided as a first stress detecting element which detects stress applied to a central portion of the semiconductor chip in plan view. The stress detecting element is preferably provided as a second stress detecting element which detects stress applied to a circumferential portion of the semiconductor chip in plan view.
