Abstract
A semiconductor device has a semiconductor substrate, an insulating film, a semiconductor element and a resistance element. The semiconductor substrate has a first trench. The insulating film covers an inner surface of the first trench. The semiconductor element has an electrode. The resistance element is electrically connected to the electrode to form a resistance to a current flowing through the electrode, and is arranged in the first trench with the insulating film therebetween. Thereby, the semiconductor device can have a resistance element that has a small footprint and can pass a large current with high reliability.
