  • Patent number: 7527698
    Abstract: A method and apparatus for removing a first liquid from a surface of a substrate is provided. A second liquid is supplied to at least part of a surface of a substrate having a rotary movement. The rotary movement has a center of rotation and an edge of rotation. The second liquid is directed from the center of rotation to the edge of rotation using a nozzle. A dry zone is created on the substrate as the position of the spray moves from the center of rotation to the edge of rotation. As a result, the first liquid and the second liquid are removed from the surface of the substrate.

  • Publication number: 20070077769
    Abstract: A method for removing organic contaminants from a semiconductor surface whereby the semiconductor is held in a tank and the tank is filled with a fluid such as a liquid or a gas. Organic contaminants, such as photoresist, photoresidue, and dry etched residue, occur in process steps of semiconductor fabrication and at times, require removal. The organic contaminants are removed from the semiconductor surface by holding the semiconductor inside a tank. The method may be practiced using gas phase processing or liquid phase processing. The tank is filled with a gas mixture, a liquid, and/or a fluid, such as water, water vapor, ozone and/or an additive acting as a scavenger (a substance which counteracts the unwanted effects of other constituents of the system).

  • Patent number: 6851435
    Abstract: A method and apparatus for dispensing a liquid on the surface of a localized zone of a substrate, for example for cleaning of etching purposes. Along with the liquid, a gaseous tensio-active substance is supplied, which is miscible with said liquid and when mixed with the liquid, reduces the surface tension of said liquid, thus containing the liquid in a local zone of the substrate surface.

  • Patent number: 6821349
    Abstract: A method and an apparatus for removing a liquid, i.e. a wet processing liquid, from at least one surface of at least one substrate is disclosed. A liquid is supplied on a surface of substrate. Simultaneously or thereafter the liquid or the substrate is locally heated to thereby reduce the surface tension of said liquid. By doing so, at least locally a sharply defined liquid-ambient boundary is created. According to the invention, the substrate is subjected to a rotary movement at a speed to guide said liquid-ambient boundary over the surface of the substrate thereby removing said liquid from said surface.

  • Publication number: 20030145878
    Abstract: An apparatus for wet cleaning or etching of flat substrates comprising a tank with an inlet opening and outlet opening for said substrates. Said tank contains a cleaning liquid and is installed in a gaseous environment. At least one of the openings is a slice in a sidewall of the tank and is present below the liquid-surface. In the tank there may be a portion above the liquid filled with a gas with a pressure being lower than the pressure within said environment. The method comprises the step of transferring a substrate through the cleaning or etching liquid at a level underneath the surface of said liquid making use of said apparatus.

    Abstract: A method and an apparatus for removing a liquid, i.e a wet processing liquid, from a surface of at least one substrate is disclosed. A liquid is supplied on a surface of substrate. Simultaneously or thereafter besides the liquid also a gaseous substance can be supplied thereby creating at least locally a sharply defined liquid-vapor boundary. The gaseous substance and the liquid can be selected such that the gaseous substance is miscible with the liquid and when mixed with the liquid yields a mixture having a surface tension lower than that of the liquid. According to the invention, the substrate is subjected to a rotary movement at a speed to guide said liquid-vapor boundary over said substrate thereby removing said liquid from said substrate.
