摘要

PROBLEM TO BE SOLVED: To provide a thin film manufacturing apparatus capable of suppressing mixing of an undesired impurity.

SOLUTION: The thin film manufacturing apparatus includes a vacuum container 11, a high-frequency antenna 13 provided in the vacuum container 11, a substrate holding unit 19 provided in the vacuum container 11 apart from the high frequency antenna 13, a plasma generating gas supply port 14 provided nearby the high frequency antenna 13, a main material gas supply port 15 provided between the plasma generating gas supply port 14 and substrate S, and doping gas supply ports 16 and 17 provided between the plasma generating gas supply port 14 and substrate S and between the main material gas supply port 15 and substrate S. The doping gas supply ports 16 and 17 are closest to the substrate S and then a doping gas is prevented from flowing backward to the antenna side, so a doping atom is prevented from sticking on the antenna etc. Consequently, the mixing of an undesired doping material as an impurity is suppressed.
