摘要:
A lateral thyristor is provided which includes a semiconductor substrate of a first conductivity type, an epitaxial layer of a second conductivity type formed on the semiconductor substrate, an anode diffusion layer of the first conductivity type formed in the epitaxial layer, a gate diffusion layer of the first conductivity type formed in the epitaxial layer, and a buried layer of the second conductivity type formed below the anode diffusion layer and extending between the semiconductor substrate and the epitaxial layer, wherein there is a region directly below the anode diffusion layer where the anode diffusion layer and the buried layer do not overlap each other, when the lateral thyristor is looked down upon in a direction perpendicular to the principal surface of the semiconductor substrate.
