THIN FILM DEPOSITION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a thin film deposition apparatus which can prevent clogging of a jet port of a raw material gas supply part to which raw material gas is supplied without influencing uniformity of a thin film formed on a substrate.SOLUTION: A thin film deposition apparatus includes: a chamber forming a vacuum environment; a substrate holding part for holding a substrate within the chamber; an electrode unit for generating plasma which is provided facing to the substrate holding part; and a raw material gas supply part provided between the substrate holding part and the electrode part which supplies raw material gas, in which the raw material gas is exposed to the plasma to be formed into a thin film on the substrate. The raw material gas supply part has a jet port to jet the raw material gas. Additionally, a film deposition cover which projects to a jet side from a jet port position is provided at least on an electrode unit side.
