Abstract
A semiconductor device may include a semiconductor substrate, an insulator film provided directly or indirectly on the semiconductor substrate, a main electrode for power provided on the insulator film, a pad for signal provided on the insulator film. The insulator film may include a cell region where the main electrode is provided and a pad region where the pad is provided. The cell region and the pad region of the insulator film each may include a contact hole. A height position of the contact hole located within the pad region may be higher than a height position of the contact hole located within the cell region. A width of the contact hole located within the pad region may be greater than a width of the contact hole located within the cell region.
