  Applications
  With added oxygen, CF4 (usually >80% mixture concentration) is used for plasma etching of polysilicon, silicon dioxide, silicon nitride, refractory metals and metal silicides. Etching and stripping of photoresists and other polymers are also major uses of CF4 (usually <20%) and oxygen mixtures.
