Patent ID: 8435905

Claim:
A manufacturing method of a semiconductor device, comprising: loading a substrate into a processing chamber; forming a thin film having a desired thickness on said substrate by setting the following (a), (b), and (c) sequentially as one cycle: (a) supplying into said processing chamber an adsorption auxiliary gas for aiding an adsorption of a source gas vaporized from a liquid source on said substrate by reacting with a ligand of said source gas and decomposing said ligand, and causing said adsorption auxiliary gas to be adsorbed on said substrate; (b) supplying said source gas into said processing chamber, causing said ligand of said source gas to react with said adsorption auxiliary gas adsorbed on said substrate and be decomposed, causing said adsorption auxiliary gas to be removed from said substrate, and causing said source gas to be adsorbed on said substrate; and (c) supplying a reaction gas into said processing chamber and causing this reaction gas to react with said source gas adsorbed on said substrate, the cycle being repeated a plurality of times; and unloading said substrate provided with said thin film from the inside of said processing chamber.
