Patent number: 6548613Abstract: The present invention provides a polymer that can be used as an anti-refelctive coating (ARC) polymer, an ARC composition comprising the same, methods for producing the same, and methods for using the same. The polymer of the present invention is particularly useful in a submicrolithographic process, for example, using KrF (248 nm), ArF (193 nm), or F2 (157 nm) laser as a light source. The polymer of the present invention comprises a chromophore that is capable of absorbing light at the wavelengths used in a submicrolithographic process. Thus, the ARC of the present invention significantly reduces or prevents back reflection of light and the problem of the CD alteration caused by the diffracted and/or reflected light. The ARC of the present invention also significantly reduces or eliminates the standing wave effect and reflective notching.Type: GrantFiled: December 22, 2000Date of Patent: April 15, 2003Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Min-Ho Jung, Sung-Eun Hong, Jae-Chang Jung, Geun-Su Lee, Ki-Ho Baik

Patent number: 5442023Abstract: This invention relates to hindered-hydroxyl functional (meth)acrylate monomers containing significant amounts of the corresponding di(meth)acrylates, and to compositions including same. The hindered-hydroxyl functional (meth)acrylate and di(meth)acrylate monomers do not require separation prior to polymerization and have utility in coating, adhesive, ink, and sealant compositions, as well as in other end uses.Type: GrantFiled: June 30, 1994Date of Patent: August 15, 1995Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: John N. Argyropoulos, Molly I. Busby

Patent number: 5389722Abstract: A hydrophilic resin is produced by a method which comprises copolymerizing a hydrophilic unsaturated monomer with 0.001 to 50 mol %, based on the amount of said monomer, of a first cross-linking agent possessing a structural unit represented by the general formula (I): ##STR1## wherein n represents an integer of at least 1, and then heat-treating the product of the copolymerization. An absorbent resin is produced by a method which comprises treating the hydrophilic resin obtained as described above, in the surface region of the resin, in the presence of a third cross-linking agent capable of reacting with the functional group of the hydrophilic resin.The absorbent ratio of the absorbent resin with respect to physiological saline solution is able to be increased to at least 20 g/g as compared to its original level by being heat-treated at a temperature of 150.degree. C. for 30 minutes.Type: GrantFiled: June 3, 1993Date of Patent: February 14, 1995Assignee: Nippon Shokubai Co., Ltd.Inventors: Kinya Nagasuna, Kunihiko Ishizaki
