ABSTRACT:
An ideal step-profile in a channel region is realized easily and reliably, whereby suppression of the short-channel effect and prevention of mobility degradation are achieved together. A silicon substrate is amorphized to a predetermined depth from a semiconductor film, and impurities to become the source/drain are introduced in this state. Then the impurities are activated, and the amorphized portion is recrystallized, by low temperature solid-phase epitaxial regrowth. With the processing temperature required for the low temperature solid-phase epitaxial regrowth being within a range of 450° C.-650° C., thermal diffusion of the impurities into the semiconductor film is suppressed, thereby maintaining the initial steep step-profile.
