Abstract:
1. A physical vapor deposition method, including: a production step of heating and evaporating an evaporation source material in a predetermined gas atmosphere or an air atmosphere in an evaporation chamber by a heating part which evaporates the evaporation source material to produce fine particles from evaporated atoms; a stirring step of stirring a powder having a particle size of not more than several tens of micrometers in a vessel of a powder supply source by causing the vessel to vibrate at not more than 1200 rpm; a mixing step of transporting the fine particles and the powder from the powder supply source to a mixing part and mixing the fine particles and the powder in the mixing part, wherein the transporting is caused by a pressure difference between the evaporation chamber and the powder supply source and a film forming chamber; and a film forming step of making the mixed fine particles and powder ride a supersonic gas stream created by a supersonic nozzle connected to the mixing part, depositing this on the substrate for film formation by physical vapor deposition, and forming a film containing the fine particles and the powder in the film forming chamber.
