Abstract
A plate high-frequency electrode for supplying a high-frequency power of the VHF band and a grounding electrode are disposed in opposition to each other at an interval of less than 8 mm in a vacuum vessel; at least a silane-based gas and nitrogen gas as source gases are introduced into a reaction space of the vacuum vessel, and a silicon nitride deposited film is formed with the pressure of the reaction space being kept at 40 to 133. Thereby, a silicon nitride film with good quality can be obtained.
