An O2 RF plasma can be used at CAMD to strip one to five microns of resist from up to 6 four inch wafers at a time.  The Bransen Asher is run at 600W at time, temperture, or manual control.

Minor modification – The Bransen Plasma Asher reduced Nitrogen purge flow for the safe ashing of thin fragile membranes
