Abstract
Embodiments of the present disclosure relates to methods, systems, and apparatus for monitoring radiation output of lamps of processing chambers. In some embodiments, a system contains a plurality of lamps coupled to a chamber, and one or more radiation sensors. Each lamp is identified with one or more zones, the radiation sensors are coupled to the chamber, where each radiation sensor is proximal at least one lamp. A controller contains instructions that, when executed, cause: the radiation sensors to convey, to the controller, information associated with radiation emitted by the lamps; the controller to analyze the information, the analyzing including: for each zone: determining a function of radiation over time; and monitoring the function for a condition associated with lamp aging; and the controller to, based on the analyzing the information, perform at least one of the following: vary input power delivered to the lamps; and generate an alert.
