Abstract:
1. A method of depositing a film, the method comprising the steps of: alternately supplying a first process gas and a second process gas that react with each other to cause an atomic layer or a molecular layer of a reaction product of the first process gas and the second process gas to deposit on a substrate in a chamber by repeating a cycle of alternately supplying the first process gas and the second process gas to the substrate once each cycle; and continuing to supply the second process gas while stopping the supply of the first process gas for a predetermined period of time after depositing the film of a predetermined thickness by repeating the cycle a predetermined number of times, wherein a cycle time of the cycle is set at a predetermined time that causes the reaction product to have a density low enough to ensure gaps and/or intrusion routes to allow the second process gas to go into the film during the step of continuing to supply the second process gas while stopping the supply of the first process gas for the predetermined period of time.
