The XeF2 etcher is a system designed to expose samples to xenon difluoride (XeF2) gas, using vacuum, in a cyclic mode. The system is computer software controlled where users can run pre-defined recipes based on # of etch cycles, etch time per cycle, XeF2 pressure, and N2 pressure. The system has automatic safety features of purging and locking fume hood in place.
This instrument has material restrictions. Consult the allowed materials list for this instrument in FOM.
