    摘要: A tertiary olefin is produced by contacting a gaseous tertiary ether usually represented by the following general formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are alkyl groups each having 1-4 carbon atoms which may be same or different and R.sup.4 is an alkyl group having 1-3 carbon atoms, with a catalyst obtained by calcining a silica-alumina compound at 700.degree.-1100.degree. C. in order to effect cracking of the tertiary ether. This reaction may be carried out in the presence of steam to result in further improvements.

    摘要: An aromatic primary hydroperoxide is produced by oxidizing a methyl-substituted aromatic compound in a liquid phase with a molecular oxygen-containing gas at a temperature of 80.degree.-150.degree. C. under a pressure of the atmospheric to 100 kg/cm.sup.2 gage in the presence of 8-300 parts by weight of an aliphatic tertiary hydroperoxide per 100 parts by weight of the methyl-substituted aromatic compound. The oxidation reaction is promoted, an aromatic primary hydroperoxide content of the reaction products is increased, whereas by-products are reduced, and a selectivity to the aromatic primary hydroperoxide is considerably increased.

    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°.
