Abstract
Methods and apparatus for detecting a vacuum leak within a processing chamber are described herein. More specifically, the methods and apparatus relate to the utilization of a spectral measurement device, such as a spectral gauge, to determine the leak rate within a process chamber while the process chamber is held at a leak test pressure. The spectral measurement device determines the rate of increase of one or more gases within the processing chamber and can be used to determine if the processing chamber passes or fails the leak test.
