发明名称 METHODS FOR EXTENDING THE LIFETIME OF PRESSURE GAUGES COUPLED TO SUBSTRATE PROCESS CHAMBERS
摘要 Methods of extending the lifetime of pressure gauges coupled to process chambers are disclosed herein. In some embodiments, the methods may include isolating the pressure gauge from a processing volume of the process chamber, increasing a moisture content of the processing volume to above a desired moisture level while the pressure gauge is isolated from the processing volume of the process chamber, reducing a moisture content of the processing volume to a desired moisture level, wherein the processing volume has a leak rate of about 2 mTorr/min or less at the desired moisture level, and exposing the pressure gauge to the processing volume after reaching the desired moisture level. In some embodiments, the moisture content of the process chamber may be increased by performing a cleaning process in the process chamber or by allowing air to enter the processing volume.
