    摘要: A pattern is formed by coating a first positive resist composition comprising a base resin, a photoacid generator, and a base generator onto a substrate to form a first resist film, patternwise exposure, PEB, and development to form a first resist pattern, heating the first resist pattern for causing the base generator to generate a base for inactivating the pattern to acid, coating a second positive resist composition comprising a C3-C8 alcohol and an optional C6-C12 ether onto the first resist pattern-bearing substrate to form a second resist film, patternwise exposure, PEB, and development to form a second resist pattern.

    摘要: A rare earth metal extractant containing, as the extractant component, dialkyldiglycol amide acid which is excellent in breaking down light rare earth elements is reacted in diglycolic acid (X mol) and an esterification agent (Y mol) at a reaction temperature of 70° C. or more and for a reaction time of one hour or more such that the mol ratio of Y/X is 2.5 or more, and is subjected to vacuum concentration. Subsequently, a reaction intermediate product is obtained by removing unreacted products and reaction residue, and an aprotic polar solvent is added as the reaction solvent. Then, the reaction intermediate product is reacted with dialkyl amine (Z mol) such that the mol ratio of Z/X is 0.9 or more and the aprotic polar solvent is removed. As a consequence, a rare earth metal extractant is efficiently synthesized at a low cost and at a high yield without having to use expensive diglycolic acid anhydride and harmful dichloromethane.

    摘要: A method for manufacturing a plate-shaped peeling member having a thin metal plate and a resin sheet adhered thereto by wrapping the resin sheet around a leading edge of the thin metal plate. The plate-shaped peeling member peels paper from a roller or a belt of an electrophotographic apparatus, with a leading edge of the thin metal plate in contact with or being adjacent to the roller or the belt. The method includes the step of stacking an adhesive agent-applied resin sheet to one main surface of a thin metal plate without pulling both end portions of the adhesive agent-applied resin sheet in a longitudinal direction thereof, with an unstuck portion left on the adhesive agent-applied resin sheet in a widthwise direction thereof and with the adhesive agent-applied resin sheet being pressurized in a longitudinal direction thereof.

    摘要: A polymer comprising recurring units of a sulfonium salt represented by formula (1) is provided as well as a chemically amplified resist composition comprising the same. R1 is H, F, methyl or trifluoromethyl, R2 to R4 are C1-C10 alkyl or alkoxy, R5 is C1-C30 alkyl or C6-C14 aryl, k, m and n are 0 to 3. The recurring units generate a sulfonic acid upon exposure to high-energy radiation so as to facilitate effective scission of acid labile groups in the resist composition. The resist composition exhibits excellent resolution and a pattern finish with minimal LER.
