Abstract
A semiconductor integrated circuit contains a resistance element, wherein a low resistance region of a first conductivity type, employed for a circuit resistance, is formed within a high resistance region of a second conductivity type, opposite to the first conductivity type. The low resistance region and the high resistance region are connected in parallel, so as to prevent the formation of a parasitic transistor and a parasitic thyristor.
