ABSTRACT:
A method to anisotropically etch a titanate wafer (16 or 39) is provided. The method includes the steps of generating a plasma (32) and mixing an organic acid reagent with the plasma (32). The titanate wafer (16 or 39) is then exposed to the plasma (32) and organic acid reagent mixture thereby etching (42) the titanate wafer (16 or 39).
