Abstract
A built-in resistor electrically connecting a trench gate electrode and a gate pad is formed of a conductive film formed on a semiconductor substrate via an insulating film. Here, a film thickness of the insulating film is larger than a film thickness of an insulating film in a trench and is smaller than an insulating film which is a field oxide film.
