Nonequilibrium Diffusion of Boron in SiC at Low …

2014-3-6 · Nonequilibrium diffusion of Boron in 3C SiC was performed using a flow of carbon vacancies. The temperature of diffusion was 1150-1250℃ and concentration of Boron in doped area reached about 1019 to 1020 cm-3. It is shown that after thermal annealing in vacuum the characteristics of fabried structures are close to those of the structures made by the conventional technology.
