摘要： A silicon nitride film is formed on a target substrate by performing a plurality of cycles in a process field configured to be selectively supplied with a first process gas containing a silane family gas and a second process gas containing a nitriding gas. Each of the cycles includes a first supply step of performing supply of the first process gas while maintaining a shut-off state of supply of the second process gas, and a second supply step of performing supply of the second process gas, while maintaining a shut-off state of supply of the first process gas. The method is arranged to repeat a first cycle set with the second supply step including an excitation period of exciting the second process gas and a second cycle set with the second supply step including no period of exciting the second process gas.

摘要： A film formation method, in a vertical batch CVD apparatus, is preset to repeat a cycle a plurality of times to laminate thin films formed by respective times. The cycle alternately includes an adsorption step of adsorbing a source gas onto a surface of the target substrates and a reaction step of causing a reactive gas to react with the adsorbed source gas. The adsorption step is arranged to make a plurality of times a supply sub-step of performing supply of the source gas to the process field with an intermediate sub-step of stopping supply of the source gas to the process field interposed therebetween, while maintaining a shut-off state of supply of the reactive gas. The reaction step is arranged to continuously perform supply of the reactive gas to the process field, while maintaining a shut-off state of supply of the source gas.

摘要： A method for using a film formation apparatus for a semiconductor process to form a thin film on a target substrate inside a reaction chamber includes performing a cleaning process to remove a by-product film deposited on a predetermined region in a gas route from a film formation gas supply system, which supplies a film formation gas contributory to film formation, through the reaction chamber to an exhaust system, by alternately repeating an etching step and an exhaust step a plurality of times in a state where the reaction chamber does not accommodate the target substrate. The etching step includes supplying a cleaning gas in an activated state for etching the by-product film onto the predetermined region, thereby etching the by-product film. The exhaust step includes stopping supply of the cleaning gas and exhausting gas by the exhaust system from a space in which the predetermined region is present.

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.
