Resist protective coating composition and patterning process
摘要:
A protective coating composition comprising a polymer of acyl-protected hexafluoroalcohol structure as a base polymer, optionally in admixture with a second polymer containing sulfonic acid amine salt in recurring units is applied onto a resist film. The protective coating is transparent to radiation of wavelength up to 200 nm.
