发明名称 Methods of proximity head brushing
摘要 A wafer preparation method is provided for producing a wet region and then a corresponding dry region on the wafer. Brushing produces the wet region on the wafer. As the brushing moves in a selected scan operation across the wafer, a generating operation forms a meniscus that follows the brushing and dries the wet region. The generating operation produces the meniscus at least partially surrounding the wet region scrubbed by the scrubbing. The controlled meniscus is formed by applying fluid to the surface of the wafer and simultaneously removing the fluid. The scan operations may be selected so the brushing scrubs the wet region and then the meniscus forms the dry region where the scrubbing took place. The scan operations include a radial scan, a linear scan, a spiral scan and a raster scan.
