Abstract

An ultraviolet light reaction system is constructed for surface cleaning/surface processing, a processing speed and an apparatus size that can not be attained by any conventional chemical reaction system, are realized, and realization of a time-sharing performance/a high-throughput performance/a compact size is intended. Using an excimer ultraviolet lamp whose light source is excimer ultraviolet rays of a wavelength that transmissive distances to air, gas, and water are 2 mm or more, respectively, surface processing (such as a surface cleaning process) of a substrate disposed in a one-by-one substrate chamber is preformed.
