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. The film formation process repeats a first cycle set that excites the nitriding gas by the exciting mechanism and a second cycle that does not excite the nitriding gas by the exciting mechanism.

摘要： A method for using a vertical film formation apparatus includes performing a coating process inside the process container without product target objects present therein to cover an inner surface of the process container with a coating film, and then performing a film formation process inside the process container accommodating the holder with the product target objects placed thereon to form a predetermined film on the product target objects. The coating process alternately supplies the first and second process gases into the process container without turning either of the first and second process gases into plasma. The film formation process alternately supplies the first and second process gases into the process container while turning at least one of the first and second process gases into plasma.
