摘要:
A system and method are disclosed which enable temperature of a substrate, such as mask or reticle, to be monitored and/or regulated. One or more temperature sensors are associated with the substrate to sense substrate temperature during exposure by an exposing source. The sensed temperature is used to control one or more process parameters of the exposure to help maintain the substrate at or below a desired temperature.
