Abstract: A semiconductor device is formed by performing an amorphizing ion implantation to implant dopants of a first conductivity type into a semiconductor body. The first ion implantation causes a defect area (e.g., end-of-range defects) within the semiconductor body at a depth. A non-amorphizing implantation implants dopants of the same conductivity type into the semiconductor body. This ion implantation step implants dopants throughout the defect area. The dopants can then be activated by heating the semiconductor body for less than 10 ms, e.g., using a flash anneal or a laser anneal.

The metal-oxide main dielectric layer can be stabilized (using, for example, a thermal or plasma treatment) to remove defects (such as carbon) therefrom and to adjust the stoichiometry of the metal-oxide main dielectric layer.

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.
