WebAug 17, 1998 · In situ x‐ray photoelectron spectroscopy (XPS), etch rate measurements, and optical emission spectroscopy have been used to examine the etching characteristics of tungsten in CF 4 /O 2 reactive ion etching plasmas. WebThe process of titanium etching in fluorinated plasma (eg, CF4/O2 glow discharges) consists in three successive steps: 1) the ablation of the "hard" stoichiometric Ti02 oxide; 2) the etching of the "soft" non-stochiometric TiOx, 3) the etching of metallic titanium. The etching rate during the first step is negligible, then it increases in the ...
