发明名称 Method of spiral resist deposition
摘要 A method of depositing a material upon a substrate is disclosed. A material, such as photoresist, is deposited upon a substrate such as a semiconductor wafer by spinning the substrate and commencing deposition at the edge of the wafer and moving inward in a spiral pattern. The method produces a more uniform coating than hitherto available.
