SPIN-ON LAYER FOR DIRECTED SELF ASSEMBLY WITH TUNABLE NEUTRALITY |
摘要 |
Techniques disclosed herein include methods for creating a directed self-assembly tunable neutral layer that works with multiple different block copolymer materials. Techniques herein can include depositing a neutral layer and then post-processing this neutral layer to tune its characteristics so that the neutral layer is compatible with a particular block copolymer scheme or schemes. Post-processing herein of such a neutral layer can modify a ratio of pi and sigma bonds in a given carbon film or other film to approximate a given self-assembly film that will be deposited on this neutral layer. Accordingly, a generic or single material can be used for a neutral layer and modified to match a given block copolymer to be deposited. |
