摘要:
A substrate supporting film to be etched is held on a rotating stage. Ultraviolet light having a wavelength of 200 nm or shorter radiated from first lamps irradiates the film in air, thereby removing an organic coatings from the film and making the surface of the film hydrophilic. A chemical solution is applied to the hydrophilic film while rotating the substrate. Ultraviolet light having a wavelength longer than 200 nm is radiated from second lamps and onto the film through the chemical solution.

To advantageously eliminate the disadvantage of attenuation of the radiant light from dielectric barrier discharge lamps by a UV transmission component, a treatment device using dielectric barrier discharge lamps is provided with a lamp chamber in which dielectric barrier discharge lamps are located and in which there is an inert gas atmosphere; a treatment chamber, in which an article to be treated is located, is provided with a treatment gas atmosphere, and a UV transmission component by which the lamp chamber and the treatment chamber are separated from one another. In each of the lamp chamber and the treatment chamber there are devices for determining the gas pressure within the respective chamber, a supply arrangement for delivering gas to the inside the respective chamber and an arrangement for discharging gas from the respective chamber. A control device regulates the pressure of the gas atmosphere within the lamp chamber and the pressure of the gas atmosphere of the treatment chamber relative to one another by determining the gas pressures of the lamp chamber and the treatment chamber.

In a dielectric barrier discharge lamp, in which a discharge vessel, in which a discharge gas forming "excimer" molecules is encapsulated, is provided with a dielectric provided with a netlike electrode and a window, through which the light goes, the first object of the invention is achieved by an arrangement in which a thickness of ends of the above-described netlike electrodes is greater than the average thickness of the entire electrode. Another object of the invention is achieved by an arrangement in which a holder incorporated in the discharge vessel has an outer dimension that is less than/equal to an outer dimension of the netlike electrodes. A further object of the invention is achieved by an arrangement by which the discharge vessel has a hollow cylindrical shape formed from an external tube and an internal tube and a means for hermetic sealing is arranged inside the internal tube.

This is achieved according to the invention by the provision of a light source device having a discharge lamp which has a generally cylindrical, coaxial double-tube arrangement of an outer tube and an inner tube, in which there is an outer electrode on the outer tube, in which there is an inner electrode on the inner tube, and in which a discharge space between the inner and outer tubes is filled with a discharge gas for formation of excimer molecules by a dielectric barrier discharge, and of a power source for operating this discharge lamp in accordance with the relationship: Vs/Vp.ltoreq.0.5 where Vs is the starting voltage and Vp is the voltage applied to the discharge lamp during steady-state luminous operation.
摘要:
A dielectric barrier discharge lamp having a generally cylindrical double-tube arrangement of an outer tube coaxially disposed about an inner tube, with an outer electrode disposed on an outside surface of the outer tube, an inner electrode disposed on an inside surface of the inner tube, and a discharge space provided between the outer tube and the inner tube which is filled with a discharge gas for formation of excimer molecules by dielectric barrier discharge achieves firm engagement of the inner electrode against the inner tube and a stable discharge over a long time even if part of the electrode corrodes due to the ozone produced or it wears. This is achieved by embodiments in which the inner electrode is a generally tubular part which is slit in an axial direction along the full length thereof. The tubular part can be a single cylindrically sheet having opposite longitudinally extending edges spaced from each other by a gap or overlapped. Alternatively, the tubular part can be formed of a pair of substantially semi-cylindrical parts which are separated by a gap between each pair of longitudinally extending edges.
