IPC: H01L21/304
Filed: 2001-11-27
Abstract: PURPOSE: To enhance accuracy and efficiency when a substrate is treated, for example, cleaned by irradiating the substrate with ultraviolet rays emitted from a dielectric barrier discharge lamp by keeping the region to be irradiated with the ultraviolet rays in an oxygen-less atmosphere. CONSTITUTION: A reductive radical £H.| and an oxidative radical £.OH| are produced by the ultraviolet rays emitted from the dielectric barrier discharge lamp 1 arranged in a treating chamber 12. A contaminant consisting of an organic substance stuck on the surface of the substrate 10 is decomposed by irradiation energy of the short-wavelength ultraviolet rays. Oxidation reaction and reduction reaction are caused between the low-molecular contaminant decomposed thus and the oxidative and reductive radicals. The air existing on the surface of the substrate 10 to be treated and in its vicinity is removed by blowing nitrogen gas from a nitrogen gas jetting nozzle 30 toward the direction opposite to the substrate conveying direction along the surface of the substrate 10 and replaced by nitrogen gas. After that, the surface of the substrate 10 and its vicinity are humidified by wet nitrogen gas in which steam and nitrogen gas are mixed and which is supplied from a wet nitrogen gas supplying nozzle 17.
