Abstract: PURPOSE:To prevent the element breakdown due to a breakdown current by a method wherein the second conductivity type well region is provided on the upper surface side of the first conductivity type substrate and the first conductivity type high concentration region in the region, further the other first conductivity type high concentration region and a gate electrode are provided in the substrate, and the first conductivity type high concentration region and the second conductivity type high concentration region P-N joined in the region with a relatively wide plane are provided in the lower surface side of the substrate. CONSTITUTION:When a high voltge such as a surge is impressed between the drain and source, depletion layers 33 and 34 generate at the P-N junction between the P type well region 22 and the N type substrate region and the P<+>-N<+> junction between the P<+> type substrate 31 and the N<+> type layer 30 which constitute a Zener diode region ZD1, respectively. An electric field concentrates at the corner of the region 22; since the region ZD1 is composed by the P-N junction of the semiconductor layers 30 and 31 both of high concentrations, breakdown occurs at the P<+>-N<+> junction of the region ZD1. At this time, a breakdown current BI uniformly flows over the entire body of the relatively wide plane of the P<+>-N<+> junction surface 35, therefore thermal concentration does not occur.
