摘要： It is an object of the present invention to make it easy to diffuse phosphorus into a silicon film and allow the phosphorus diffusion concentration to be easily controlled by varying the timing at which the dopant gas is allowed to flow. A silicon wafer 10 on whose surface an amorphous silicon film 12 has been formed is placed in a diffusion furnace. After this, phosphine (PH3) or a mixed gas containing phosphine is allowed to begin flowing over the wafer 15 and the phosphorus is diffused into the silicon film 12 before the amorphous silicon film 12 crystallizes and changes into a polysilicon film.
