Abstract

PURPOSE:To reduce a chip by introducing a one conductive type impurities with a part of a gate electrode provided on a semiconductor substrate as a mask, then introducing reverse conductive type impurities with a part of the same gate electrode as a mask. CONSTITUTION:An n<-> type epitaxial layer 2 is provided on the n<+> type Si substrate 1. The gate electrode 7 is provided via a gate oxide film 6. A central part is covered by a photoresist layer. Then B is implanted with the gate electrode as a mask. A channel region 4 is formed by heat treatment. Then the photoresist is removed, and P is implanted with the gate electrode as a mask again (13 is the implanted region). A source and drain region is formed by heat treatment. In this method, sicne the entire semiconductor region can be formed in a self-aligning mode, the gate length and the channel length can be shortened, and the input capacity can be reduced.
