SILICON NITRIDE FILM OF SEMICONDUCTOR ELEMENT, AND METHOD AND APPARATUS FOR PRODUCING SILICON NITRIDE FILM

摘要

Disclosed are: a silicon nitride film of a semiconductor element, which is formed by applying a bias power and appropriately controls hydrogen leaving from the silicon nitride film; and a method and apparatus for producing a silicon nitride film. Specifically disclosed is a silicon nitride film which is formed on a substrate (19) by plasma processing and used in a semiconductor element. If the silicon nitride film is in contact with a film (41) to which supply of hydrogen is required to be shut off, the silicon nitride film is configured of a biased SiN (31) that is formed by applying a bias to the substrate (19) and an unbiased SiN (32) that is formed without applying a bias to the substrate (19) and the unbiased SiN (32) is arranged on the side on which the silicon nitride film is in contact with the film (41).
