Susceptor to showerhead gaps must be checked and/or adjusted each time a process chamber is serviced to obtain the highest film uniformity. Legacy susceptor leveling methods which use dial indicators do not capture chamber deflections that result from evacuation, because they can only be used while the chamber is open and assume that the showerhead is parallel to the top of the chamber. MCT-Series uses touchable distance sensing and wireless communication to display gap information on a personal computer external to a closed and evacuated chamber
