Abstract
A first electrode film is electrically connected to a source region of a semiconductor substrate, and disposed over a main surface of the semiconductor substrate. A second electrode film is electrically connected to a gate electrode, and disposed over the main surface. A third electrode film is disposed over the main surface away from the first electrode film. A protective dielectric film is disposed over the main surface, covers only a portion of each of the first electrode film and the second electrode film and covers at least portion of the third electrode film, and is made of a thermosetting resin. The main surface has a peripheral region and an inner region enclosed by the peripheral region, and the protective dielectric film has a peripheral portion covering the peripheral region and has a first inner portion crossing the inner region and covering at least portion of the third electrode film.
