Environmentally friendly wafer production: NF3 remote microwave plasma for chamber cleaning
For NF3 remote microwave plasma chamber cleaning, compared with CF4 cleaning processes, a reduction of emission of gases relevant to global warming is observed. At the same time a reduction of operating costs for the abatement is possible. The presented data show a very high destruction and removal efficiency for NF3 and its major decomposition product F2 in an ESCAPE abatement system.
