    摘要: The present invention relates to a novel catalyst used for homopolymerization of an olefin of 2 or more carbon atoms or for copolymerization of two or more olefins of 2 or more carbon atoms, as well as to a process for producing an olefin polymer using said catalyst. High molecular olefin polymers can be produced at a high yield, by homopolymerizing an olefin or copolymerizing olefins using a catalyst system consisting of a transition metal compound of the general formula M(R).sub.l (OR').sub.m X.sub.n-(l+m) and an aluminoxane or a catalyst system comprising a transition metal compound of the general formula M(R).sub.l (OR').sub.m X.sub.n-(l+m), an aluminoxane and an organic compound having at least 2 hydroxyl groups.

    摘要: There is disclosed a patterning process including steps of at least: forming a photoresist film on a substrate; exposing the photoresist film to a high energy beam; developing by using a developer; forming a photoresist pattern; and then forming a spacer on the photoresist pattern sidewall, thereby forming a pattern on the substrate, a patterning process, wherein at least the photoresist pattern having the hardness of 0.4 GPa or more or the Young's modulus of 9.2 GPa or more as a film strength is formed, and a pattern is formed on the substrate by forming a silicon oxide film as the spacer on the photoresist pattern sidewall. There can be provided a patterning process without causing a deformation of a resist pattern and an increase in LWR at the time of forming a silicon oxide film on a photoresist pattern.

    摘要: A patterning process includes (1) coating and baking a first positive resist composition to form a first resist film, exposing, post-exposure baking, and alkali developing to form a first resist pattern, (2) applying a resist-modifying composition to the first resist pattern and heating to modify the first resist pattern, (3) coating and baking a second positive resist composition to form a second resist film, exposing, post-exposure baking, and alkali developing to form a second resist pattern. The modified first resist film has a contact angle with pure water of 50°-85°.
