Patent ID: 8039404

Claim:
A producing method of a semiconductor device comprising: a first step of supplying a first reactant to a substrate accommodated in a processing chamber to cause a ligand-exchange reaction between a ligand of the first reactant and a ligand as a reactive site existing on a surface of the substrate; a second step of removing a surplus of the first reactant from the processing chamber, a third step of supplying a second reactant to the substrate to cause a ligand-exchange reaction to change the ligand after the exchange in the first step into a reactive site; a fourth step of removing a surplus of the second reactant from the processing chamber; a fifth step of supplying a plasma-excited third reactant to the substrate to cause a ligand-exchange reaction to exchange a ligand which has not been exchange-reacted into the reactive site in the third step into the reactive site; and repeating the first to fifth steps until a film having a predetermined thickness is formed on the surface of the substrate.
