摘要：

We investigated the stability of NF3 plasmas for in situ chamber cleaning in a production plasma-enhanced chemical vapor deposition reactor. An rf power threshold, normalized by NF3 molar number (P-nn) and NF3 flow rate (P-nf), is observed to be PnnPnf=39 (W/mu mol)(W/sccm) for stable plasmas with high NF3 destruction efficiency. This is rationalized by the energy required to maintain sufficient electron-ion pair creation in an electronegative discharge. (C) 2004 American Institute of Physics.
