Doped Silicon by LPCVD | Tystar

Dopants such as phosphine and boron trichloride can be added to the process gas to adjust conductivity and stress. Doped polysilicon requires caged wafer boats for better uniformity. Phosphorus decreases the deposition rate while boron increases it. This in situ doping is more uniform through the film thickness than can be achieved by sequential processing steps, and it is also done at a lower
