The original (fast switching and with a maximum flow of 1200 sccm) SF<sub>6</sub> MFC was causing problems for a long a time so it was replaced by two new MFC's.
* SF6-1: Fast switching MFC for Bosch processes with a maximum flow rate of 600 sccm. It sits in the position of the old 1200 sccm MFC on top of the plasma source.* SF6-2: Normal MFC for continuous processes with a maximum flow rate of 100 sccm. It is installed in the gas cabinet next to the Ar MFC.
