Abstract: A method for reducing parasitic junction field effect transistor resistance, applicable to a high power device having a semiconductor substrate layer, is provided, including providing a plurality of hard masks on a top surface of the semiconductor substrate layer. Each hard mask has a bottom plane and a tilt sidewall such that an acute angle is formed there in between.

A width of the upper surface is greater than that of the lower surface. Therefore, the present invention achieves to control a parasitic JFET region characterized by having a wider bottom and a narrower top, thereby reducing its resistance thereof. Meanwhile, since a bottom angle of the body region is increased, breakdown voltage of the device is increased as well.
