Abstract: A method of delivering two or more mutually-reactive reaction gases when a predetermined film is deposited on a substrate, and a shower head used in the gas delivery method, function to increase the film deposition rate while preventing formation of contaminating particles. In this method, one reaction gas is delivered toward the edge of the substrate, and the other reaction gases are delivered toward the central portion of the substrate, each of the reaction gases being delivered via an independent gas outlet to prevent the reaction gases from being mixed. In the shower head, separate passages are provided to prevent the first reaction gas from mixing with the other reaction gases by delivering the first reaction gas from outlets formed around the edge of the bottom surface of the shower head. The other reaction gases are delivered from outlets formed in the central portion of the bottom surface of the shower head. Accordingly, one of the mutually-reactive gases is delivered toward the central portion of the substrate, and the others are delivered toward the edge of the substrate.
