초록

The purpose of this study is to reveal the mechanism of wafer touch polishing by high purity colloidal silica slurry containing organic surfactants such as HEC (hydroxyl-ethyl cellulose). The effect of surfactant concentration on wafer touch polishing was studied with the aim of improving roughness on wafer surface after polishing. As a result, the level of haze and micro-roughness are decreased with the decrease of surfactant concentration.
