发明名称 METHOD FOR SMOOTHING WAFER SURFACE AND APPARATUS USED THEREFOR
摘要 <p>Disclosed is a method for smoothing the surface of at least one side of a wafer which is obtained by slicing a semiconductor ingot. In this method, a fluid is applied according to projections of the wafer surface, thereby reducing the projections. Alternatively, a fluid is applied over the wafer surface, thereby smoothing the entire surface of the wafer while reducing the projections in the wafer surface.</p>
