发明名称 Method of fabricating semiconductor device
摘要 Disclosed is a method of fabricating a semiconductor device that includes both an enhancement-mode FET and a depletion-mode FET. The method includes forming an opening in a gate electrode for the depletion-mode FET. The opening is located in or in the vicinity of one of the overlapping regions in which the gate electrode extends over active regions. The method further includes ion-implanting dopant impurities into the active regions at an oblique angle using the gate electrode as a mask, thereby to form the doped region that is located under the opening and continuously extending from one of the opposite sides of the gate electrode to the other.
