Polysiloxane compounds and positive resist compositions
摘要:
The invention provides a novel polysiloxane compound, typically polyhydroxybenzylsilsesquioxane, having some hydroxyl groups replaced by acetal groups and optionally acid labile groups. The polysiloxane compound is useful as an alkali soluble polymer for positive resist material.
