Publication number: 20010024765Abstract: A resist composition is prepared by reacting an alkali-soluble polymer having a phenolic hydroxyl or carboxyl groups with a vinyl ether compound in an aprotic solvent, such as propylene glycol monomethyl ether acetate, in the presence of an acid catalyst, suspending the reaction by the addition of a base, and directly adding a photoacid generator to the reaction solution. When a dialkyl dicarbonate is used in stead of the vinyl ether compound, a resist composition is prepared by carrying out the reaction in the presence of a basic catalyst and adding a photoacid generator directly to the reaction. Thus resist compositions can be prepared without isolating or purifying an alkali-soluble polymer which has been substituted by a catalytic reaction.Type: ApplicationFiled: April 2, 2001Publication date: September 27, 2001Inventors: Hiroshi Okazaki, Georg Pawlowski, Satoru Funato, Yoshiaki Kinoshita, Yuko Yamaguchi

Patent number: 6132117Abstract: A printing apparatus, a control method therefor, and a medium on which the control method is stored, enable selection of a resume operation to be performed when the printing apparatus resumes operation following an off-line state. The resume operation to be performed after an off-line state is determined by a command received from a host device according to the cause for the off-line state. The resume operation thus determined is performed when the printing apparatus goes on-line again following the off-line state. A marker indicating a particular location in a continuous data stream can be set. If the marker is placed at the beginning of a particular data stream, printing can be resumed from the beginning of the data stream after recovery from an off-line state. By also storing various printer definitions (settings) when a marker is set, the printing apparatus can also be restored to the printer definitions in use when the printer went off-line.Type: GrantFiled: March 25, 1999Date of Patent: October 17, 2000Assignee: Seiko Epson CorporationInventors: Kazuko Fukano, Yoshiaki Kinoshita

Patent number: 5852128Abstract: Acid-labile group protected hydroxystyrene polymers having recurrent pendant groups such as 1-(2-methanecarbonyl oxyethoxy)ethoxy group and 1-(2-N-methylcarbamatoethoxy) ethoxy group. A resist containing the polymer, a photo acid generator, a base, additives and a solvent is sensitive to UV, electron beam and X-ray. In the resist, acid is formed in the exposed area during irradiation, which deprotects acid-labile group catalytically during application of post-exposure baking. Positive patterns are formed after development using an alkaline solution.Type: GrantFiled: September 3, 1997Date of Patent: December 22, 1998Assignee: Clariant AGInventors: Munirathna Padmanaban, Georg Pawlowski, Yoshiaki Kinoshita, Hiroshi Okazaki, Seiya Masuda, Satoru Funato, Tetsu Yamamoto
