    Abstract: A MISFET is formed to include: a co-doped layer that is formed over a substrate and has an n-type semiconductor region and a p-type semiconductor region; and a gate electrode formed over the co-doped layer via a gate insulation film. The co-doped layer contains a larger amount of Mg, a p-type impurity, than that of Si, an n-type impurity. Accordingly, the carriers (electrons) resulting from the n-type impurities (herein, Si) in the co-doped layer are canceled by the carriers (holes) resulting from p-type impurities (herein, Mg), thereby allowing the co-doped layer to serve as the p-type semiconductor region. Mg can be inactivated by introducing hydrogen into, of the co-doped layer, a region where the n-type semiconductor region is to be formed, thereby allowing the region to serve as the n-type semiconductor region. By thus introducing hydrogen into the co-doped layer, the p-type semiconductor region and the n-type semiconductor region can be formed in the same layer.
