I enabled drytek2 to use Isotropic Si Etch recipe for 30 seconds and first two times were good. However, when I tried to do third time of Si etch it suddenly didn't work. The machine keep venting and I cannot hear any hissing sound when I press Cycle Start button. I set the RF power level, chamber pressure, gas flow rates exactly same as the numbers in the manual but I don't know why it went down.
