  • Publication number: 20140199638
    Abstract: After a developing step, a substrate is spun at high speeds without supplying a cleaning liquid to a surface of the substrate. This causes a large centrifugal force to act on a developer on a resist film. Consequently, the developer can be removed rapidly from the surface of the substrate. As a result, development can be stopped at an expected timing. Moreover, a circuit pattern having an expected dimension can be obtained. At this time, a dissolved product is also removable with the developer from the substrate. This can avoid failure in development caused by the dissolved product. Consequently, suitably maintained quality of negative development can be achieved with a reduced usage amount of the cleaning liquid.

    Abstract: The invention provides a method capable of preventing the occurrence of collapse of resist pattern accompanied by size reduction in pattern dimensions can be prevented when processing a resist film having been exposed and formed on the surface of a substrate, and in which there is no fear that posterior processes are adversely affected. In the step of processing a resist film having been exposed and formed on the surface of a substrate, a developer mixed with a hydrophobizing agent is fed onto the resist film on the substrate surface; or before rinsing the resist film having been processed, a solvent containing a hydrophobic resin is fed onto the resist film on the substrate surface. Thus, a resist exposed surface is made to be hydrophobic before the rinsing, and thereafter rinsed and dried by spinning.

  • Patent number: 7018784
    Abstract: The invention relates to a process for amplifying structured resists. The process permits a subsequent increase in the etch resistance and a change in the structure size of the resist even in the case of ultrathin layers. The chemical amplification is carried out in a solvent that is so nonpolar that it does not dissolve the structured resist or dissolves it only to an insignificant extent. Because of the lower surface tension of these solvents, the danger of a collapse of these structures is additionally avoided.

  • Patent number: 6759184
    Abstract: A process for the post-exposure amplification of resist structures uses amplification of resist structures of fluorinated resist polymers by structural growth of the structures by targeted chemical bonding of fluorinated oligomers. In the first step, a fluorine-containing resist is applied to a substrate. After exposure and development of the resist, bonding of an amplification agent chemically amplifies the resist structures. A fluorine-containing amplification agent is preferably used to achieve an improved reaction between polymer and amplification agent due to the improved miscibility of the molecular chains.

  • Patent number: 6645705
    Abstract: The present invention is a photographic element which includes a support, at least one silver-halide emulsion layer superposed on the support and a processing-solution-permeable overcoat overlying the silver-halide emulsion layer that becomes water-resistant in the final product, without requiring lamination or fusing. The presence, in the coating composition, of a compound comprising a blocked copolymer of ethylene oxide and propylene oxide has been found to improve wet durability, prevent the retention of iron, and improve the conversion of the overcoat to a water-resistant layer during processing. The present invention is also directed to a method of making a photographic print involving developing the photographic element.
