摘要
In situ low phosphorus doped silicon films are deposited onto glass substrates by low-pressure chemical vapor deposition method. The deposition parameters, temperature, total pressure, and pure silane gas flow are, respectively, fixed at 550-degrees-C, 0.08 Torr, and 50 sccm. The varying deposition parameter is phosphine/silane mole ratio; when this ratio varies from 2 X 10(-6) to 4 X 10(-4), the phosphorus concentration and the resistivity after annealing, respectively, vary from 2 X 10(18) to 3 X 10(20) atoms cm-3 and from 1.5-OMEGA-cm to 2.5 X 10(-3)-OMEGA-cm.
