摘要:
A liquid coating composition for forming a silica-based coating film on the surface of a substrate such as a semiconductor silicon wafer. A partial hydrolysis product of an alkoxy silane and an alkoxy or phenoxy compound of pentavalent antimony are dissolved in an organic solvent. As compared with a trivalent antimony compound used in the prior art, the pentavalent antimony compound as an additive is very effective in respect of the improvements in the uniformity and increased thickness of the silica-based coating film prepared from the coating composition as well as storage stability of the coating composition over time.
