Abstract

According to this present invention, a semiconductor device includes source and drain diffusion layers, and a gate electrode formed on a substrate between the source diffusion layer and the drain diffusion layer. In addition, antioxidant films are respectively formed on the source diffusion layer and the drain diffusion layer. These antioxidant films are used for controlling a diffusion rate of an impurity contained in the source diffusion layer and the drain diffusion layer.
