Upon manufacture of a semiconductor device provided with a source region and a drain region formed by activating, through anneal, an n-type first dopant ion-implanted in a p-type device forming area provided in a semiconductor layer formed on an insulator, and a body region, (a) ion implantation of Ar in a boundary region between the source and drain regions to be formed, which corresponds to a region lying in a predeterminate area for forming the body region, and (b) high-temperature anneal for partly recovering crystal defects produced by the ion implantation of the Ar at a temperature higher than the anneal for activation of the first dopant are carried out prior to the ion-implantation of the first dopant.
