  • Publication number: 20140162194
    Abstract: Methods and apparatus for forming a sacrificial during a novel process sequence of lithography and photoresist patterning are provided. In one embodiment, a method of processing a substrate having a resist material and an anti-reflective coating material thereon includes depositing an organic polymer layer over the surface of the substrate inside a process chamber using a CVD technique. The CVD technique includes flowing a monomer into a processing region of the process chamber, flowing an initiator into the processing region through one or more filament wires heated to a temperature between about 200° C. and about 450° C., and forming the organic polymer layer. In addition, the organic polymer layer is ashable and can be removed from the surface of the substrate when the resist material is removed from the surface of the substrate.

  • Patent number: 6489090
    Abstract: A black-and-white photographic developing composition has improved stability and is more compatible with the environment when discarded. The composition includes one or more ascorbic acid developing agents and a preservative (such as a sulfite) and is essentially free of hydroquinone and similar developing agents. It comprises an &agr;-ketocarboxylic acid stabilizing agent at a molar ratio to the ascorbic acid developing agent of from about 0.05:1 to about 2.5:1, and at a molar ratio to the preservative of from about 0.05:1 to about 6.25:1.

  • Publication number: 20020164551
    Abstract: Stable, single-part photographic bleach-fixing “precursor” compositions comprise one or more iron-ligand complexes, one or more thiosulfates as the sole fixing agents, and optionally, a sulfite preservative. At least 50 mol % of the iron in the composition is in the form of Fe(II). This composition can be used directly in photoprocessing, or used as a regenerator when mixed with bleach-fixing overflow to provide a replenishing solution. Because the Fe(II) compounds are precursor bleaching agents, they must be oxidized to Fe(III) for active bleaching prior to or during the photographic processing operations.

  • Patent number: 6468721
    Abstract: The method and apparatus supplies processing solution directly to the surface of a web of sensitized material by means of a movable applicator. The web and applicator are moved relative to each other to enable good mixing of the solution on the surface. The movable applicators can be moved in and out of contact with the material as required so that the process can be varied.

  • Patent number: 6455236
    Abstract: Compositions and methods of making photographic one-part bleach-fix liquid concentrates, packaged in a single unit, wherein the bleaching agent is a polyvalent metal oxidizing agent are described. A thiocyanate salt is added in an amount sufficient to provide one-part bleach-fix liquid concentrates that are homogeneous, remain free of crystallized precipitates for extended periods of time, and that retain effective oxidizing potential during extended periods of storage. Alternatively, the present invention provides for compositions and methods of making stable bleach-fix liquid concentrates, suitable for dilution to working strength solutions, using a polyvalent metal oxidizing bleaching agent, at least one fixing agent, and a source of phosphate ions. Precipitation, which occurs when an iron (III) bleaching agent is reduced by components of the concentrate, is prevented by the addition of thiocyanate and/or phosphate ions.

  • Patent number: 6440653
    Abstract: A method of producing a photographic image in an imagewise exposed photographic material comprising one or more silver halide emulsion layers comprises developing the material with a developer solution containing a silver halide developing agent, applying to the surface of the developed material a solution of a sulphite compound that reacts with oxidised developing agent and prevents further development, and applying to the surface of the developed material a solution of an oxidant that oxidises any remaining developing agent, wherein said sulphite compound is present in an amount sufficient to react with all the oxidised developing agent and said solutions of sulphite and oxidant are applied to the material by means other than immersion in a tank.

  • Publication number: 20020115028
    Abstract: An image forming assembly and method utilizes a laminate processing sheet. The laminate processing sheet is applied on an emulsion side of an exposed photosensitive film which includes sprocket holes along opposing edges. In a first feature of the present invention, a width of the laminate processing sheet is confined to an image area between the opposing sprocket holes, so as to reduce or eliminate the possibility of processing marks in or around an area of the opposing sprocket holes In a further feature of the present invention, an absorbing sheet can be applied to the backside of the photosensitive film, to absorb any excess processing or wetting solution that is applied to the photosensitive film. This also aids in reducing or eliminating unwanted processing marks at the sprocket holes or an area in the vicinity of the sprocket holes.

  • Publication number: 20020115027
    Abstract: A method and system for environmental control in film processing is disclosed. In general, photographic film is coated with a processing solution, such as a developer solution, and is then developed within a controlled air environment. In the preferred embodiments, the temperature and humidity within the air environment is strictly controlled, which allows the development process to be more accurately and consistently controlled. This also allows fewer processing chemicals to be used and reduces harmful effluents caused by photographic film processing.

  • Patent number: 6432623
    Abstract: A method of processing a photographic imaging element to obtain a protective overcoat is disclosed, which overcoat provides, in the final product, resistance to fingerprints, common stains, and spills. More particularly, the present invention involves a processing-solution-permeable overcoat that becomes water and stain resistant in the photochemically processed product. The overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer. During development or thereafter, before drying, the water-soluble polymer is removed to a significant extent. Subsequently, the imaged element is dried at an elevated temperature to facilitate coalescence of the overcoat to thereby provide enhanced stain resistance and water-resistance.

  • Publication number: 20020102503
    Abstract: A method for processing a silver halide photographic material comprises the steps of loading the material into a chamber adapted to hold the material therein, introducing a metered amount of a first processing solution into the chamber, processing the photographic material with the first processing solution, introducing a metered amount of a second processing solution which is other than a second part of the first processing solution into the chamber without removing the first processing solution so that at least part of the total volume of the second processing solution is provided by the first processing solution and processing the photographic material with the second processing solution, the total volume of solution for each processing stage being spread over the whole area of the photographic material in a repetitive manner to enable uniform processing.

  • Patent number: 6426269
    Abstract: A method, and a system for employing the method, for providing a modified optical proximity correction (OPC) for correcting distortions of pattern lines on a semiconductor circuit wafer. The method comprises producing a mask having one or more pattern regions, and producing the semiconductor circuit wafer from the mask. The pattern regions include one or more non-edge pattern regions located adjacent to other of the non-edge pattern regions on the mask. The pattern regions further include one or more edge pattern regions located at or near an area on the mask not having the other non-edge pattern regions. The edge pattern regions have widths calculated to minimize the variance in dimensions between one or more pattern lines on the semiconductor circuit wafer formed from them and one or more pattern lines on the semiconductor circuit wafer formed from the non-edge pattern regions.
