For the dry etching step using the pseudo-Bosch process, the sidewall angle is largely dependent on the SF 6 /C 4 F 8 gas … WebMay 1, 1984 · A taper dry etching technique for molybdenum films is proposed. The dry etching characteristics of oxygen‐doped Mo films in a discharge are studied. It is found that oxygen‐doped Mo films are etched at a higher rate than oxygen‐undoped Mo film and that, in oxygen‐doped Mo films, undercutting occurs differently from oxygen‐undoped Mo film.
