Patent ID: 8105957

Claim:
A method of producing a semiconductor device comprising: forming a thin film by (1) supplying a first reactant to a substrate accommodated in a processing chamber causing a first ligand-exchange reaction between a ligand of the first reactant and a ligand as a reactive site existing on a surface of the substrate; (2) removing any surplus of the first reactant from the processing chamber; (3) supplying a second reactant to the substrate causing a second ligand-exchange reaction changing the ligand after the first ligand-exchange into a reactive site; (4) removing any surplus of the second reactant from the processing chamber; supplying a plasma-excited third reactant to the substrate causing a ligand-exchange reaction exchanging a ligand which has not been exchange-reacted into the reactive site in the second ligand-exchange; and repeating the thin film forming and the plasma processing steps until a thin film having a predetermined thickness is formed on the surface of the substrate.
