Process for curing low-dielectric constant material

Abstract

Provided is a low-dielectric constant material curing process including irradiating a low-dielectric constant material on a semiconductor substrate with ultraviolet rays. In the low-dielectric constant material curing process, the ultraviolet light source is a fluorescent lamp including: a light-emitting tube sealed and filled with a discharge gas containing xenon gas; a pair of electrodes for inducing a discharge in the interior space of the light-emitting tube; a dielectric material being interposed between the interior space and at least one of the pair of electrodes; and a phosphor layer formed on a surface of the light-emitting tube and containing a phosphor that is excited by light generated from the discharge gas by a discharge in the interior space. The phosphor emits ultraviolet rays having a wavelength within a range of 180 to 300 nm.
