Abstract: A semiconductor device that reduces the occurrence of a leakage current by forming a doped layer in each of an NMOS region and a PMOS region on an SOT substrate, and completely separating the doped layer of the NMOS region from the doped layer of the PMOS region using the element isolation layer is provided. The semiconductor device includes a first region and a second region adjacent to the first region, a substrate including a first layer, an insulating layer on the first layer, and a second layer on the insulating layer, a first doped layer on the second layer in the first region and including a first impurity, a second doped layer on the second layer in the second region and including a second impurity different from the first impurity, and an element isolation layer configured to separate the first doped layer from the second doped layer, and in contact with the insulating layer.
