| Zusammenfassung: | A semiconductor device includes a plurality of diodes including a substrate of a first conductivity type biased to a reference potential, a well region of a second conductivity type formed in a surface region of the substrate, and a first diffusion region of the first conductivity type formed in a surface region of the well region, wherein the plurality of diodes have sizes of at least two kinds and are cascade-connected to each other. |
