Abstract
PURPOSE:To improve the operating speed of a semiconductor device and to reduce the power consumption of the device by forming a tapered insulating film on the peripheral side surface of a gate electrode formed on a substrate and introducing impurity for imparting conductivity with the gate electrode and the insulating film as masks. CONSTITUTION:A field oxidized film 2 and a gate oxidized film 3 are formed on a P type Si substrate 1, and a gate electrode 4 is formed. After a CVD-SiO2 film 5 is accumulated on the overall surface, the film 5 and the film 3 are etched to expose the gate electrode 4 and the substrate 1. Then, a tapered SiO2 film 6 is formed on the peripheral side surface of the gate electrode 4. With the remaining gate electrode as a mask phosphorus is diffused, and an insulated gate FET in which the superposition of n<+> type source and drain regions 7, 8 with the gate electrode is zero can be formed. In this manner, the operating characteristics can be improved with reduced power consumption in an MOS type semiconductor device.
