Abstract

A method and system for providing a semiconductor device is disclosed. The method and system include depositing an antireflective coating (ARC) layer having antireflective properties. The method and system also include depositing a capping layer on the ARC layer. The capping layer reduces a susceptibility of the ARC layer to removal while allowing the ARC layer to substantially retain the antireflective properties.
