New Surface Treatment Method for Dielectric Anti-Reflective Coating (DARC) to Shrink Photoresist Critical Dimension (CD)
20170371247 · 2017-12-28 ·

A KrF (248 nm) photoresist patterning process flow is disclosed wherein photoresist patterns having a sub-100 nm CD are formed on a dielectric antireflective coating (DARC) thereby lowering cost of ownership by replacing a more expensive ArF (193 nm) photoresist patterning process. A key feature is treatment of a DARC such as SiON with a photoresist developer solution that is 0.263 N tetramethylammonium hydroxide (TMAH) prior to treatment with hexamethyldisilazane (HMDS) in order to significantly improve adhesion of features with CD down to about 60 nm. After the HMDS treatment, a photoresist layer is coated on the DARC, patternwise exposed, and treated with the photoresist developer solution to form a pattern therein. Features that were previously resolved by KrF patterning processes but subsequently collapsed because of poor adhesion, now remain upright and intact during a subsequent etch process used to transfer the sub-100 nm features into a substrate.
