DEPOSITION OF a-Si : H BY HOMOGENEOUS CVD

Abstract
A new method (HOMOCVD) of amorphous hydrogenated silicon (a-Si : H) deposition is reported in which SiH4 is thermally decomposed in the vapor state to produce SiH2 as the reactive intermediate. The resulting films contain up to 30 atomic % hydrogen and properties comparable to glow discharge-produced material. Since the reactive intermediate and its chemistry are unambiguously known, HOMOCVD provides insight into the nature of the deposition process
