The vacuum is set to be as high as Torr. Then, the heating boat 3 is heated by a resistor, an electron beam, a laser beam, etc., and the AU powder put into the heating boat 3 is evaporated. evaporated A
One molecule is deposited on the treatment object 4 placed on one side of the heating boat 3 to form a predetermined A-pattern thin film lower layer. After a predetermined period of time has elapsed, the leak valve 7 is opened and the atmosphere is introduced to change the vacuum deposition pressure in the vacuum reaction tank 1 to about 10-2 Torr.
