Epitaxial PbZr0.52Ti0.48O3 (PZT 52/48) heterostructures incorporating SrRuO3 electrodes were patterned through a single step epitaxial lift-off technique without using any acidic etching. This procedure enables patterning of high temperature grown perovskite multilayers through the use of a pre-patterned AlOx mask which acts as a high temperature sacrificial template. Ferroelectric properties of structured PZT grown on (001) SrTiO3 substrates as well as on commercially important platinized Si were investigated in capacitor configuration analogous to structures previously prepared through wet etching. In addition, the patterning technique is shown to be compatible with e-beam lithography for preparation of sub-micron device structures consisting of ferroelectric perovskite materials.
