Novel sulfonyldiazomethanes, photoacid generators, resist compositions, and patterning process |
摘要 |
A chemical amplification type resist composition comprising a specific sulfonyldiazomethane containing long-chain alkoxyl groups has many advantages including improved resolution, improved focus latitude, minimized line width variation or shape degradation even on long-term PED, minimized debris left after coating, development and peeling, and improved pattern profile after development and is thus suited for microfabrication.
