SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device including a protective Zener diode which is formed via an insulation film on a semiconductor substrate where a switching element is formed and which has less occupied area and less dynamic resistance.SOLUTION: A semiconductor device 100 having a protective Zener diode 33 having less occupied area and less dynamic resistance can be provided by repeating a plurality of unit devices 33a each having a p(74)/n(75)/n(76) structure.
