Abstract
Process chambers and methods for calibrating components of a processing chamber while the chamber volume is under vacuum are described. The process chamber includes a motor shaft connected to the process chamber with a plurality of motor bolts. A support plate is positioned under the chamber floor to accommodate for deflection of the chamber floor due to vacuum conditions within the chamber volume. A bellows assembly extending from the chamber floor to the support plate maintains vacuum conditions within the chamber.
