We presented the etch results of indium-tin oxide thin films by using SF$_{6}$/O$_2$gas electron cyclotron resonance plasma and conducted X-ray phtoelectron spectroscopy and quadrupole mass spectrometer analyses for the etch characteristics. The etch rate of the films was greatly dependent on that of oxygen which was the major constituent element of the films. The oxygen was removed by the forms like $O_2$or SOF$_2$. We examined the ratio of atomic content of O and In and the change of this ratio was related to the removal rate of InF$_{x}$ and the S-metal bonding.ing.
