Abstract:
Provided is a modified hydrogenated polysiloxazane prepared by reacting hydrogenated polysiloxazane with a silane compound selected from the group consisting of polysilane, polycyclosilane and a silane oligomer. The modified hydrogenated polysiloxazane has small molar ratio of nitrogen atoms with respect to silicon atoms, and can markedly decrease layer shrinkage ratio during manufacturing a silica-based insulating layer when applied in a composition for manufacturing the silica-based insulating layer.

Abstract:
The present invention relates to a method for forming a silica film, a silica film formed by the same, and an electronic device including the silica film. The method for forming a silica film comprises the following steps of: applying a siloxane compound; applying a silicon-nitrogen-containing compound; and converting the silicon-nitrogen-containing compound into silica by processing the siloxane compound and the silicon-nitrogen-containing compound by heat treatment at the same time.
Abstract:
Provided is a composition for forming silica based insulating layer which includes polysilazane hydroxide or polysiloxazane hydroxide, and has 1200 ppm or less of concentrate of cyclic compound having 400 or less of weight-average molecular weight. The composition for forming silica based insulating layer can reduce thickness dispersion when forming the silica based insulating layer, thereby reducing film deficiency after chemical mechanical polishing (CMP) when manufacturing a semiconductor.
