Abstract:
1. A semiconductor integrated circuit, comprising: a diode including a first polarity-type diffusion layer and a second polarity-type diffusion layer which is disposed next to the first polarity-type diffusion layer in a first direction in a plan view; and a second polarity-type contact region surrounding, in a plan view, four sides of the diode including the first polarity-type diffusion layer and the second polarity-type diffusion layer, the contact region having a first contact region extending along the first direction and a second contact region extending along a second direction perpendicular to the first direction in a plan view, wherein each of the first polarity-type diffusion layer and second polarity-type diffusion layer of the diode has a plurality of contact holes for electrical connection with an external device, and the second contact region extending along the second direction of the contact region has a plurality of contact holes and the first contact region extending along the first direction has no contact hole, in a plan view.
