High rate deposition of a-Si:H films has become one of the key techniques for low-cost, large-scale production of thin film devices. Hydrogenated amorphous silicon films were fabricated with a thermocatalytic PCVD method of which the deposition rate was up to 1.5 nm/sec. The Heterojunction Monitored Capacitance method was employed to determine the midgap-state densities in the undoped semiconductor film from high frequency C-V characteristics. Experimental results showed that the thermocatalytic PCVD method is an effective way to produce high-rate deposited a-Si:H films.
