Light-absorbing antireflective layers with improved performance due to refractive index optimization
Patent number: 6274295Abstract: The invention consists of a light absorbing top antireflective layer that reduces the swing curve amplitude for photoresist materials used in the semiconductor industry. The coating may be water based but is not necessarily so. The advantage of a water-based coating is its ease of use, since it can be applied without intermixing to the softbaked photoresist, and is removed in the development step, so that process complexity is only minimally increased. One problem that has been associated with the existing non-absorbing antireflective coatings is that the optimum swing curve reduction is only achieved at a very low refractive index. The advantages of a dyed coating are a) that the refractive index of the top coat can additionally be lowered by making use of anomalous dispersion effects if the dye is chosen judiciously, and b) that it is possible to achieve the optimum swing curve reduction at a higher refractive index of the top coat.Type: GrantFiled: March 8, 1999Date of Patent: August 14, 2001Assignee: Clariant Finance (BVI) LimitedInventors: Ralph R.

Patent number: 6071673Abstract: The present invention provides a method for the formation of a pattern, which comprises applying an antireflective coating film-forming composition solution comprising (A) a compound which undergoes crosslinking reaction when irradiated with actinic rays and (B) a dye to a substrate to form a coating film thereon, entirely irradiating the coating film with actinic rays to form an antireflective coating film, applying a resist solution to the antireflective coating film, drying the coated material to form a resist layer, and then subjecting the coated material to lithographic treatment to form a resist pattern on the antireflective coating film. The method enables the formation of a resist pattern having an excellent dimensional accuracy and section shape without causing the formation of an intermixed layer between the resist composition and antireflective coating film.Type: GrantFiled: August 21, 1998Date of Patent: June 6, 2000Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Etsuko Iguchi, Toshimasa Nakayama, Taiichiro Aoki

Patent number: 6048677Abstract: The present invention is a photographic element which includes a support having a first side and a second side, at least one light sensitive emulsion layer superposed on the first side of the support, a transparent magnetic layer superposed on the second side of the support. The transparent magnetic layer includes magnetic particles and a film forming binder. An outermost abrasive lubricant layer overlies the transparent magnetic layer. The outermost abrasive lubricant layer is formed from a non-aqueous coating composition of a composite wax particle, an abrasive particle and an organic solvent. The composite wax particle is composed of a wax phase having a wax having a melting point of greater than 30.degree. C. the wax being greater than 80% by weight of the wax phase and a non-crosslinked polymer phase free of chemically bonded acid groups.Type: GrantFiled: December 28, 1998Date of Patent: April 11, 2000Assignee: Eastman Kodak CompanyInventors: Janglin Chen, Yongcai Wang, Vito A. DePalma, Robert O. James

Patent number: 6048678Abstract: The present invention is an imaging element which contains a support, an image forming layer superposed on the support and an outermost protective layer superposed on the support. The protective layer is a cellulosic material and a composite wax particle. The wax particle is composed of a wax phase and a non-crosslinked polymer phase. The wax phase includes a wax having a melting point of greater than 30.degree. C. The non-crosslinked polymer phase contains from 10% to 80% by weight of a mono-alpha, beta-ethylenically unsaturated monomer capable of addition polymerization to form a water soluble homopolymer. In a preferred embodiment the protective layer overlies an antistatic layer.Type: GrantFiled: December 28, 1998Date of Patent: April 11, 2000Assignee: Eastman Kodak CompanyInventors: Dwight W. Schwark, Yongcai Wang, Robert J. Kress

Patent number: 6048662Abstract: This invention relates to antireflective coatings comprising polymeric polyoxyalkylenated colorants. More particularly, the present invention relates to antireflective coatings for utilization in forming thin layers between reflective substrates and photoresist coatings. Such antireflective coatings are very useful and beneficial within the production and fabrication of semiconductors through photolithographic procedures due to the liquid, non-crystallizing nature of polyoxyalkylenated colorants, and the lack of potentially damaging counterions, metals, and/or electrolytes within the inventive antireflective colored coatings. The inventive coatings may also be applied on lenses, mirrors, and other optical components. Methods of forming such antireflective coatings are also contemplated within this invention.Type: GrantFiled: December 15, 1998Date of Patent: April 11, 2000Inventors: John D. Bruhnke, John G. Lever
