Abstract:
According to an embodiment, in the present invention, provided is a monomer for a hardmask composition, which secures gap-fill and flatness properties while having etch resistance. The present invention relates to a monomer for a hardmask composition denoted by chemical formula 1, a hardmask composition including the monomer, and a forming method of patterns using the same. In chemical formula 1, A, A′, A″, L, L′, X, X′, m and n are described as defined in the specification.
Abstract:
Provided are a manufacturing method of a filler for filling a gap, comprising manufacturing hydrogenation polysilazane by putting 50-70 parts by weight of ammonia based on 100 parts by weight of halo-silane at a rate of 1 to 15 g/hr after injecting the halo-silane into an alkaline solvent, a filler for filling a gap manufactured by the manufacturing method, and a manufacturing method of a semiconductor capacitor using the same.
Abstract:
Provided is a composition for forming a silica-based insulating layer which comprises a thermal base generator protected by a protective group decomposed by heat. The composition for forming a silica-based insulating layer reduces a shrinkage factor of a base material and reduces a shrinkage factor of the silica-base insulating layer, and improves the storage stability, when substituted to a dense silica glass by an oxidation reaction at a high temperature.
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.
