Abstract

The invention provides a novel method of depositing an amorphous silicon film wherein a high frequency discontinuous discharge is carried out to decompose a silane system gas for a chemical vapor deposition for depositing an amorphous silicon film under conditions of a cyclic frequency of 500 Hz or more and a duty ratio of 30% or less.
