发明名称 Etching process for organic anti-reflective coating
摘要 A process for selectively removing an anti-reflective coating (ARC) in the manufacturing of semiconductor integrated circuits using an oxygen-free plasma of one or more fluorine containing compounds, chlorine and an optional inert carrier gas. The process renders effective etching of the anti-reflective coating while maintaining dimensional control of a previously etched photoresist.
