    Abstract: In a method for wet-chemical treatment of surfaces of a material. a pulse-like spray jet of treatment fluid is directed against the surface of the material. This causes a pronounced impact action against the base of a structure to be processed so that the amount of treatment time which is necessary is substantially reduced. The pressure-free and accelerated outflow of the treatment fluid from the structure channels in the pauses between pulses results in the flanks of the structures or circuit-board conductors being subjected to less wet-chemical processing than in the prior art. In case of chemical etching the result is a smaller undercutting.

  • Patent number: 7189305
    Abstract: A method for moving resist stripper across the surface of a semiconductor substrate that includes applying a wet chemical resist stripper, such as an organic or oxidizing wet chemical resist stripper, to at least a portion of a photomask positioned over the semiconductor substrate. A carrier fluid, such as a gas, is then directed toward the semiconductor substrate so as to move the resist stripper across the substrate. The carrier fluid may be directed toward the substrate as the resist stripper is being applied thereto or following application of the resist stripper. A system for effecting the method is also disclosed.

  • Patent number: 7105074
    Abstract: A substrate treating apparatus is provided for eliminating wasteful consumption of a treating solution in a treating mode in which the treating solution is delivered in a strip form to a substrate from a treating solution delivery nozzle sweeping over the substrate. In a first aspect of the invention, collecting vessels are arranged around a developing cup surrounding a wafer supported by a wafer holder. The collecting vessels collect part of a developer delivered from a discharge opening of a developer delivery nozzle outwardly of a surface of the wafer. In a second aspect of the invention, collecting vessels are arranged below a developer delivery nozzle, with collecting openings of the collecting vessels opposed to a discharge opening or openings of the delivery nozzle. The collecting vessels are moved longitudinally of the discharge openings according to a position of the developer delivery nozzle relative to the wafer.
