Patent ID: 7927982

Claim:
A silicon-based thin film mass-producing method for mass-producing a silicon-based thin film in which silicon-based thin films are deposited on film formation portions using a silicon-based thin film mass-producing apparatus, the apparatus including a chamber having a gas inlet for feeding a raw material gas for depositing the silicon-based thin films, a plurality of supporting electrodes which are provided in the chamber and capable of supporting the film formation portions, a plurality of counter electrodes provided so as to face the corresponding supporting electrodes with a space therebetween, and a DC pulse voltage application circuit which applies a DC pulse voltage between the supporting electrodes and the corresponding counter electrodes, the method comprising the steps of: (a) supporting the film formation portions on the supporting electrodes such that a space is formed between the surfaces of the film formation portions and the corresponding counter electrodes; and (b) controlling the internal pressure of the chamber to a pressure of 1 kPa or less and applying a DC pulse voltage between the counter electrodes and the corresponding supporting electrodes by the DC pulse voltage application circuit to generate plasma while feeding the raw material gas into the chamber, so as to deposit the silicon-based thin films on the film formation portions.
