The purpose of this work is to clarify the relationship between some of the properties of MOS capacitors passivated by fluoride-containing zinc borosilicate glasses and the hydroxyl content of the glasses. Substitution of ZnF2 for ZnO progressively decreases the OH^- absorption coefficient and the C-V curve shift, △(↑-)VGVG” height=”17″ width=”29″> , in the MOS capacitors decreased. A good recovery without hysteresis was observed in the MOS capacitors passivated by glasses with a small concentration of OH^-ions.
