Abstract

Abstract The present invention relates to vacuum processing equipment for processing a wafer in a vacuum, and film coating or forming equipment and method for forming a film on a wafer wherein radiation measurement and temperature control of the wafer is carried out by using an infrared radiation thermometer. Based upon the radiation measurement, heating and/or cooling of the wafer during processing is carried out.
