The RIE system is computer controlled.  The operator runs programmable recipes where process pressure, gases, and RF power can be defined.  The process chamber is 11 inches in diameter and the sample electrode is water cooled.  The vacuum system consists of a dual stage rotary vane mechanical pump and a turbo molecular pump.  The maximum RF power for this system is 500 Watts.

This instrument has material restrictions.  Consult the allowed materials list for this instrument in FOM.
