摘要
Low temperature bodings of Cu with the gas cluster ion beam (GCIB) irradiations were studied. Since GCIB exhibits surface smoothing effects without severe damage, it is promising for the surface activated bonding (SAB). Ar-GCIB irradiation at oblique incidence removed native oxide on Cu films without roughening. With increasing the acceleration voltage of Ar-GCIB, the surface roughness of Cu decreased, which resulted in lowering the bonding temperature.
