摘要:
Method of forming a lightly phosphorous doped silicon film. A substrate is provided. A process gas comprising a phosphorous source gas and a disilane gas is used to form a lightly phosphorous doped silicon film on the substrate. The diluted phosphorous source gas has a phosphorous concentration of 1%. The phosphorous source gas and the disilane gas have a flow ratio less than 1:100. The lightly phosphorous doped silicon film has a phosphorous doping concentration less than 1×1020 atoms/cm3.
