  • Patent number: 6485893
    Abstract: A surface-active agent is applied onto a surface to be processed of a wafer, onto which a chemical solution of an antireflection film is applied, thereby forming an antireflection film with the thickness of, for example, about 100 nm. Subsequently, the surface-active agent is applied onto a surface of the antireflection film, onto which a resist solution is applied, thereby forming a resist film with the thickness of, for example, about 500 nm. By applying a coating solution such as the chemical solution of the antireflection film, the resist solution and the like onto the surface-active agent as described above, the surface tension of the coating solution is decreased by the action of the surface-active agent, and the coating solution spreads approximately parallel to the surface of the wafer along the top surface of the wafer. Thus, the required coating amount of the coating solution is reduced, and the amount of the chemical solution can be saved.

  • Publication number: 20020160323
    Abstract: A method has been disclosed for preparing a co-precipitated microcrystalline dye dispersion, the absorption spectrum of which exceeds the summoned spectra of individually dispersed dyes, which comprises, as consecutive preparation steps: adding to one vessel, an amount of at least one pentamethine oxonol-type barbituric acid filter dye having ionizable sites in its molecular structure; adding thereto an aqueous alkaline solution in an amount sufficient to completely dissolve the said filter dye while stirring the solution thus formed; adding in another vessel, to an amount of at least one pyrrole type filter dye, an amount of water, followed by adding of an aqueous alkaline solution and a surfactant; followed, after having completely dissolved (under stirring conditions) the said pyrrole type filter dye, by adding to the solution thus formed in the other vessel, the solution formed in the one vessel; adding an aqueous acidic solution up to a pH of less than 3.

  • Patent number: 6465162
    Abstract: Photothermographic materials provide images having improved stability from browning. The improved image stability is achieved by including an image stabilizing compound in the support, a backside layer on the support or in a layer associated with a backside layer. The most useful backside layer for this purpose is an antihalation layer. These compounds are present in the backside layer in an amount sufficient to provide an increase in blocking power of at least 0.01.

  • Patent number: 6461776
    Abstract: Disclosed are methods for forming a resist pattern which solve a problem caused by halation and interference phenomena due to reflected light from the substrate. A first method forms between the substrate and resist film an anti-reflective film whose photoabsorbance of the exposure light is greater on the substrate surface side than on the resist surface side. A second method forms between the substrate and resist film a two-layer anti-reflective film made up of an upper interference film for the exposure light and a lower film having higher exposure light absorbance than the upper film and functions as a light shielding film. A third method forms between the substrate and resist film a two-layer anti-reflective film consisting of a lower film that reflects exposure light and an upper film that is an interference film for the exposure light.

  • Patent number: 6455240
    Abstract: A method of reducing the tendency toward formation of coating non-uniformities in the coating of multilayer photographic elements is disclosed. More particularly, the present invention involves the coating of a non-gelatin coating over a topmost gelatin layer in a photographic element. In one embodiment, a processing-solution-permeable overcoat is simultaneously coated with the emulsion layers onto a photographic substrate, which overcoat becomes water and stain resistant in the photochemically processed product. In the latter embodiment, the overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer.
