Zusammenfassung:Methods and apparatus for detecting ultraviolet light are provided herein. For example, an ultraviolet (UV) process chamber includes a vacuum window or a transparent showerhead; a UV light source disposed above one of the vacuum window or the transparent showerhead and configured to generate and transmit UV light into a process volume of the UV process chamber; and a first UV sensor configured to measure at least one of emissivity from the UV light source or irradiance of the UV light transmitted into the process volume and to transmit a signal corresponding to a measured at least one of emissivity from the UV light source or irradiance of the UV light to a controller coupled to the UV process chamber during operation.
