Abstract

Disclosed is modified hydrogenated polysiloxazane prepared by reacting hydrogenated polysiloxazane with a silane compound selected from polysilane, polycyclosilane, and a silane oligomer. The modified hydrogenated polysiloxazane has a small mole ratio of nitrogen atoms relative to silicon atoms and may remarkably deteriorate a film shrinkage ratio when included in a composition for forming a silica-based insulation layer to form a silica-based insulation layer.
