摘要: Disclosed is a method for using a film formation apparatus to form a silicon nitride film by CVD on target substrates while suppressing particle generation. The apparatus includes a process container and an exciting mechanism attached on the process container. The method includes conducting a pre-coating process by performing pre-cycles and conducting a film formation process by performing main cycles. Each of the pre-cycles and main cycles alternately includes a step of supplying a silicon source gas and a step of supplying a nitriding gas with steps of exhausting gas from inside the process container interposed therebetween. The pre-coating process includes no period of exciting the nitriding gas by the exciting mechanism.
