To realize the high-rate and low-damage sputtering of a Si surface, the effect of irradiating an ethanol cluster ion beam on a Si surface was investigated. The sputtering depths in Si substrates induced by the ethanol cluster ion beam irradiation were larger than those in SiO(2) substrates, which was due to a chemical sputtering effect. The lattice disorder and the surface roughness of the Si substrates decreased with increasing retarding voltage. (C) 2009 The Japan Society of Applied Physics
