Low-temperature dry etching of metal oxides and ZnS via formation of volatile metal β-diketonate complexes

Abstract
The reactions of CuO, PbO, ZnO, ZnS, V2O5, PbTiO3, PbZrO3, and YBa2Cu3O7–x, with 1,1,1,5,5,5-hexafiuoroacetyl-acetone result in formation of the corresponding metal β-diketonates with etch rates of 1 µm min–1for mixed copper(I)/(II) oxide films.
