Abstract
A semiconductor substrate includes a base substrate, a first epitaxial layer having a first conductivity type on the base substrate, a second epitaxial layer having the first conductivity type on the first epitaxial layer, a first well region having a second conductivity type different from the first conductivity type, in the first epitaxial layer and the second epitaxial layer, and a second well region which is spaced apart from the first well region and has the second conductivity type, in the first epitaxial layer and the second epitaxial layer, wherein a doping concentration of the first epitaxial layer is greater than a doping concentration of the second epitaxial layer, and a depth of each of the first well region and the second well region is greater than a thickness of the second epitaxial layer.
