Ultraviolet and vacuum ultraviolet radiators for use in the manufacture of semiconductors are provided which have improved lifetimes, improved distribution of radiation generation, improved distribution of emitted radiation, increased efficiency of radiation emission, and improved means for cooling. The radiators have novel electrodes, novel electrode configurations, novel means for distributing plasmas between electrodes, and have novel cooling means. These features enable the miniaturization of the radiators permitting high-intensity and uniform radiation exposure of planar surfaces. The radiators are used in the pre-treatment of semiconductor surfaces, the deposition of semiconductor thin films, and the post-deposition processing of semiconductor thin films.

Deposition rates of undoped silicate glass dielectric layers on thermal oxide are increased by pre-treating the thermal oxide layer with electromagnetic radiation in the ultraviolet (UV) and/or vacuum ultraviolet (VUV) wavelengths. The surface smoothness of the resulting films are also increased by pre-treating films with UV and/or VUV radiation. Furthermore, the gap filling abilities of the undoped silicate glass films are increased by pre-treating the thermal oxide with UV and/or VUV radiation. New equipment and methods are presented for exposing semiconductor devices to UV and/or VUV radiation, and for enhancing the deposition rates and film quality for semiconductor manufacture. Semiconductor devices incorporating the new methods are also described.
