ABSTRACT:
A method for using a film formation apparatus includes performing film formation of a product film selected from the group consisting of a silicon nitride film and a silicon oxynitride film on a target substrate within a reaction chamber of the film formation apparatus; and unloading the target substrate from the reaction chamber. Thereafter, the method includes first heating an inner surface of the reaction chamber at a post process temperature while supplying a post process gas for nitridation into the reaction chamber, thereby performing nitridation of a by-product film deposited on the inner surface of the reaction chamber; then rapidly cooling the inner surface of the reaction chamber, thereby cracking the by-product film by a thermal stress; and then forcibly exhausting gas from inside the reaction chamber to carry the by-product film, thus peeled off from the inner surface.
