Paper Abstract
The rate of etching of Nb oxydes in plasmas of CF4-O2 and CF4-H2 gas mixtures has been investigated. The etch curves of the oxydes thermally grown at different temperatures ( 673 K - 1023 K ) and times ( 10 - 45 min ) show similar behavior as these of pure Nb films, but with etch rates a factor of 2-3 higher. Fluorine radicals seem to be the main reactants in the etch chemistry. The etching is anisotropic and the end-point detection can be accurately made by "in situ" laser interferometry.
