  • Patent number: 6588122
    Abstract: A method and apparatus for the treatment of surfaces of substrates of organic or inorganic materials, reactive fragments such as radicals or ions are produced by ultraviolet radiation from at least one ultraviolet radiator disposed at a given distance. The apparatus has a gas-filled, elongated discharge chamber whose walls are formed by a dielectric, and the ultraviolet radiator is provided on the side facing away from the discharge chamber with at least one electrode. During irradiation, a translational and/or rotatory relative movement is performed between the substrate and the ultraviolet radiator at a comparatively slight distance between radiator and substrate surface, in order to achieve, in a simple manner, an intense and uniform illumination of the surface being irradiated. The treatment is directed especially to silicon substrates or glass substrates.

  • Publication number: 20020112739
    Abstract: For the treatment of surfaces of substrates of organic or inorganic materials, reactive fragments—especially radicals or ions—are produced by ultraviolet radiation; the ultraviolet radiation is performed by at least one ultraviolet radiator disposed at a given distance, with a gas-filled, elongated discharge chamber whose walls are formed by a dielectric, which is provided on the side facing away from the discharge chamber with at least one electrode; during the irradiation a translational and/or rotatory relative movement is performed between the substrate and the ultraviolet radiator at a comparatively slight distance between radiator and substrate surface, in order to achieve, in a simple manner, an intense and uniform illumination of the surface being irradiated.
