A double tubed coaxial line type microwave plasma CVD system has been developed for a-Si:H film deposition using hydrogen and argon gases with pure SiH//4 gas as the material gas. The film quality was evaluated as a function of the plasma condition. A high-quality film can be fabricated under hydrogen plasma because a large amount of hydrogen radicals covers the film surface, thereby causing a thermal structural relaxation of silane radicals. This relaxation results when the silane radicals increase their surface mobility after the soft landing on the film surface.
