Abstract

Abstract PURPOSE:To form a source-drain diffusion layer only at a desired place without an impurity being diffused to the inner part under a gate electrode. CONSTITUTION:In the manufacture of MOSFET, a point defect region 26 is formed beforehand at a place, into which an impurity is desired to be introduced, by the implantation of electrically inert Si ion through thermal diffusion method and the impurity is anisotropically diffused by the speed-increasing diffusion through this point defect region 26 so that a source-drain diffusion layer 27 is formed.
