  • Patent number: 9110376
    Abstract: A system and method for photoresists is provided. In an embodiment a photoresist is developed. Once developed, the photoresist is slimmed using either a direct slimming technique or an indirect slimming technique. In a direct slimming technique the slimming agent is either an alkaline solution or a polar solvent. In the indirect slimming technique a hydrophobic material is diffused into the photoresist to form a modified region and the modified region is then removed.

  • Patent number: 8865396
    Abstract: A developing method including a developing step in which, while a wafer horizontally held by a spin chuck is being rotated, the wafer is developed by supplying a developer onto a surface of the wafer, wherein provided before the developing step is a pre-wetting step in which, simultaneously with the developer being supplied from a first nozzle that is located on a position near a central part of the surface of the rotating wafer, a deionized water as a second liquid is supplied from a second nozzle that is located on a position nearer to an outer peripheral part of the wafer than the first nozzle, to thereby spread out the developer in the rotating direction of the wafer by a wall that is formed by the deionized water flowing to the outer peripheral side of the wafer with the rotation of the wafer.

  • Publication number: 20130309615
    Abstract: A method for patterning a substrate with reduced defectivity is described. Once a pattern is formed in a layer of radiation-sensitive material using lithographic techniques, the pattern formed on the substrate is post-treated. The post-treating of the pattern in the layer of radiation-sensitive material is performed to reduce a roughness of the pattern. The post-treating includes performing a treatment process on the pattern to alter a solubility of an exposed surface of the pattern, wherein the treatment process involves performing a first chemical treatment of the pattern using a liquid-phase chemical solution containing a first surfactant, or exposing said pattern to second EM radiation different than said first EM radiation. Following the treatment process, the post-treating includes hard baking the pattern, and performing a second chemical treatment of the pattern using a vapor-phase chemical solution to reduce the roughness.

The movement speed of the nozzle is higher than a case where a nozzle with a small-diameter circular nozzle is used, and this enables a development time to be reduced. Further, the thickness of a developing solution on a substrate can be reduced, so that the developing solution can be saved.

    Abstract: There is provided a developer for use in a one-step process for the development of exposed film resulting in an exposurewise pattern of silver particles which are large enough to be used as printing elements in ink-printing techniques, providing a wide range of densities in the developed film. The developer is based on a buffered system of a developing agent, a sulfinic acid salt of the type HO-R-SO.sub.2.M..times.H.sub.2 O where R is a hydrocarbyl group and M is a cation, and a formaldehyde source, with conventional adjuvants such as anti-fogging agents and the like. Instead of the sulfinic acid salt defined above there may be used any compound which upon dissociation in a aqueous medium results in the same active ionic species.

  • Patent number: 4525449
    Abstract: A method of color reversal treatment of an exposed silver halide photographic material is disclosed. The method involves treating the exposed material with 2 both type black-and-white developing solutions. The first solution contains a compound represented by the general formula (I):R.sub.2 --S--R.sub.1).sub.d --S--R.sub.2 (I)wherein R.sub.1 represents an alkylene group having 2 to 10 carbon atoms, which may have ether bonds, R.sub.2 represents an alkyl group having 2 to 10 carbon atoms which alkyl group may have substituents, ether bonds or ester bonds, and d represents an integer of 0 to 3. The second black-and-white developing solution is a conventional solution. By utilizing the two solutions and specifically the first solution containing the compound of general formula (I) it is possible to obtain good photographic images having a high maximum density and good color balance.

  • Patent number: 4474871
    Abstract: A method for processing a silver halide photographic material having at least one silver halide emulsion layer on at least one side of a support is disclosed. The method is characterized by pretreatment with a solution carried out prior to a development-processing. The solution being substantially unable to cause a development reaction though it contains a developing agent. The method improves the covering power of developed silver without deteriorating the physical properties of the silver halide photographic material.

  • Patent number: 4361644
    Abstract: The disclosed method relates to a method for recording flow boundary layers in liquid media by photochemical means. According to the invention, surfaces which can be developed in a plane and to which a photographic film sheet is cemented are exposed under steady-state conditions to the flow of a liquid medium containing a dissolved agent reacting with the photo gelatin layer. The liquid medium may contain agents furnishing HS-ions or agents capable of dissolving silver halide or reducing silver halide. If a photographic film sheet is used, the silver ions of which are reduced to silver, the flow exposure is performed with an agent having oxidizing and dissolving action. With the method disclosed, half-tone photograms of flow boundary layers in liquids can be recorded.

  • Patent number: 4250249
    Abstract: For developing residual-moisture photographs according to the wet-film technique, a pre-treatment with a first solution of about 5% ethanolic NaOH is performed first at about 13.degree. C. After the alkali exchange, the exposed film passes through a bath at a bath temperature of 50.degree. C. with a hydroquinone-containing photographic developer. This "Two-bath wet developing method" takes place in daylight. The developed, fixed, rinsed and dried film can be evaluated directly.

  • Patent number: 4192764
    Abstract: A method for depositing a metal on a surface is disclosed. The method comprises treating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal and a radiation-sensitive reducing agent for the salt to form a sensitized surface. The sensitized surface is exposed to a source of light radiation to reduce the metal salt to a reduced metal salt species. Either or both of the preceding sensitizing or radiation exposing steps is restricted to a selected pattern on the surface to form a catalytic real image capable of directly catalyzing the deposition of a metal thereon from an electroless metal deposition solution. The catalytic real image is treated with a stabilizer comprising (a) a reducing agent for the non-noble metal ions of said reducible salt, (b) a complexing agent and (c) an accelerator to at least stabilize the catalytic real image.

  • Patent number: 4181750
    Abstract: A method of depositing a metal on a surface is disclosed. The method comprises coating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal. The coated surface is selectively treated to reduce the metal salt to metallic nuclei to form a catalytic pattern thereon capable of directly catalyzing the deposition of a metal on the nuclei from an electroless metal deposition solution. The selectively treated surface is then exposed to a stripping solution comprising an organic acid selected from (a) a carboxylic acid having a structural formula of ##STR1## where R is a member selected from the hydrogen radical, H, and an alkyl group having 1 to 3 carbon atoms, (b) citric acid and (c) a mixture of any of the foregoing acids, to essentially remove portions of the coated surface which have not been selectively treated.
