Abstract
Abstract A novel raddery organopolysilsesquioxane having lower alkyl groups and alkenyl groups as the side chains and, if necessary, having aryl groups and/or hydrogen atoms bonded as the side chains can be produced by adding water to a solution of a lower-alkyltrihalogenosilane, an alkenyltrihalogenosilane, and, if necessary, an aryltrihalogenosilane and/or a trihalogenosilane in an organic solvent, and heating the resulting mixture. The aforesaid organopolysilsesquioxane can be used for forming a patterned surface-protecting layer or insulating layer for a semiconductor device, in the form of a mixture with a compound which generates crosslinking-reaction-active species upon irradiation with light or an ionizing radiation.
