Abstract (en)

[origin: EP2006888A2] Oxygen gas, for example, is introduced into a film forming chamber, and high-frequency power is supplied to a plurality of monopole antennas arranged above a silicon substrate (101) in the film forming chamber to generate a plasma of the introduced oxygen gas, thereby supplying atomic oxygen (123) onto the surface of an aminosilane molecular layer (102). This plasma generation is performed for about 1 sec. With this operation, the adsorption layer (102) adsorbed onto the surface of the silicon substrate (101) is oxidized, thereby forming a silicon oxide layer (112) corresponding to one atomic layer of silicon on the surface of the silicon substrate (101).
