Abstract:
1. A method for patterning a layered substrate, comprising: loading a substrate into a coater-developer processing system; coating the substrate with a photoresist material to form a photoresist material layer on the substrate; patterning the photoresist material layer to form a photoresist pattern on the substrate; transferring the substrate to a deposition processing system; and depositing a neutral layer over the photoresist pattern and exposed portions of the substrate, wherein the deposition processing system is a gas cluster ion beam (GCIB) system, the neutral layer is deposited using GCIB deposition of gas cluster ions formed from a first gas mixture, and the first gas mixture is tuned to set the chemical properties of the neutral layer for subsequent directed self-assembly (DSA) patterning.
