| The chamber has cooled down from bake 5 and I took the first set of data. The pressure measured during the RGA measurements reached 9.98 e-8 torr. The data shows that the chamber got dirtier, however this has been the case for every first scan after a bake so I assume there are still some more hydrocarbons to be vacuumed out and that the second scan will most likely give a better idea of where the chamber is at. After turning off the RGA the pressure immediately dropped to 7.4 e-8 torr and was still dropping. |
