    Abstract: A method is disclosed for manufacturing a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). The method includes providing a substrate containing an epitaxial layer, forming a gate oxide layer and a polysilicon layer on the epitaxial layer, and forming a photoresist layer on the polysilicon layer and a gate region pattern in the photoresist layer. The method also includes forming a gate region by etching the polysilicon layer using the gate region pattern in the photoresist layer as a mask. The etching is performed in such a way that the gate region has a lateral surface receding at a predetermined length relative to the gate region pattern in the photoresist layer. Further, the method includes forming a body region by ion implantation and dopant drive-in using the photoresist layer as a mask such that an overlapping area between the body region and the gate region can be reduced based on the predetermined receding length.
