Abstract:
1. A manufacturing method of a semiconductor device comprising the steps of: carrying a substrate into a reaction chamber; processing the substrate by feeding a first source gas obtained by vaporizing a first source which is prepared by mixing plural kinds of liquid sources, and a second source gas obtained by vaporizing a second source which is prepared by mixing plural kinds of liquid sources at a mixing ratio different from that of the first source, or composed of one kind of liquid source to the substrate; and carrying the substrate after processing out of the reaction chamber, wherein the plural kinds of liquid sources constituting the first source are a Hf liquid source and a Si liquid source, the one kind of liquid source constituting the second source is either of the Hf liquid source or the Si liquid source, and the process means to form a Hf silicate film; and a mixing ratio of the Si liquid source and the Hf liquid source in the first source (Si liquid source/Hf liquid source) is set to be in the range of from 100 to 1000.
