METHOD FOR DEPOSITING SILICON NITRIDE FILM, COMPUTER-READABLE STORAGE MEDIUM, AND PLASMA CVD DEVICE

摘要

Provided is a method for depositing a silicon nitride film in a plasma CVD device which introduces microwaves into a process chamber by a planar antenna having a plurality of apertures, and the method including setting the pressure in the process chamber within a range from 10 Pa to 133.3 Pa and performing plasma CVD by using film formation gas including a silicon containing compound gas and a nitrogen gas while applying an RF bias to the wafer by supplying high-frequency power with an output density within a range from 0.009 W/cm2 to 0.64 W/cm2 per unit area of a wafer from a high frequency power supply to an electrode in a holding stage on which the wafer is arranged.
