Abstract:
1. A method for forming a thin film for a semiconductor device, the method including steps of: supplying a first reactant to a chamber to chemically adsorb the first reactant onto a substrate, the first reactant being bubbled by a first gas that is preheated to form a first reaction gas that then is supplied to the chamber; purging the chamber to remove residues on the substrate having the first reactant chemically adsorbed; and forming the thin film by means of chemical displacement by supplying a second reactant to the chamber to chemically adsorb the second reactant onto the substrate, wherein the thin film comprises one of a single atomic thin film formed of Ti, Ta, Ru, Ir, Rh, Mo, Al, Cu, Pt, W or Ag, a single atomic oxide formed of HfO
