Abstract

A protection diode includes: a semiconductor substrate; a well region of a first conductivity type in the semiconductor substrate; a gate side diffusion region of a second conductivity type in the semiconductor substrate and joined to the well region; a grounding side diffusion region of the second conductivity type in the semiconductor substrate, separated from the gate side diffusion region, and joined to the well region; a gate side electrode connected between a gate of a transistor and the gate side diffusion region; a grounding electrode connected to the grounding side diffusion region; and an insulating film on the well region. The grounding electrode extends to the well region on the insulating film.
