Anti-reflective coating containing sulfur atom

摘要

There is provided an anti-reflective coating forming composition comprising a solid content and a solvent, wherein a proportion of sulfur atom in the solid content is 5 to 25 mass %. The anti-reflective coating obtained from the composition has a high preventive effect for reflected light, causes no intermixing with photoresists, and can use in lithography process by use of a light having a short wavelength such as F2 excimer laser beam (wavelength 157 nm) or ArF excimer laser beam (wavelength 193 nm), etc.
