Semiconductor device

Abstract

According to one embodiment, an electrostatic discharge semiconductor device includes one or more wiring layers first disposed over a substrate, including: a wiring electrically connected at a first connecting point of a pad, a second wiring electrically connected at a second connecting point of a ground wiring, and a third wiring electrically connected at a third connecting point of the ground wiring; a first transistor formed in the substrate comprising a first diffusion region electrically connected to the first wiring, a second diffusion region electrically connected to the second wiring, and a gate electrically connected to the ground wiring; and a second transistor formed in the substrate comprising the first diffusion region electrically connected to the first wiring, a third diffusion region electrically connected to the third wiring, and a gate electrically connected to the ground wiring, wherein, a first resistance value of a first current pathway leading from the first connecting point to the second connecting point via the first transistor is different from a second resistance value of a second current pathway leading from the first connecting point to the third connecting point via the second transistor.
