CLEAN POCL3
Problem: Conventional POCL3 process causes corrosion of scavenger system and can lead to contamination by POCl gasses into the clean room.
Solution: Clean POCL3 with partial pressure redirects the flows of POCL3 to come IN and OUT of the process tube through the source cabinet. It is condensed safely away from the clean room and operators allowing for easy disposal and clean disposal.
