Abstract
Disclosed are: a method for producing a silicon nitride film, wherein generation of blisters at the periphery of a substrate is suppressed when a silicon nitride film is formed through application of a bias power; and an apparatus for producing a silicon nitride film. Specifically disclosed are a method and apparatus for producing a silicon nitride film, wherein a silicon nitride film used for a semiconductor element is formed on a substrate by plasma processing. In the method and apparatus for producing a silicon nitride film, a bias is applied to the substrate at time (b), and a starting material gas SiHfor the silicon nitride film is started to be supplied at time (b) after the application of the bias.
