Abstract

Epitaxially grown oxides of both SrTiO3 (STO) and YBa2Cu3O7-δ (YBCO) have been removed from their growth substrate and transferred for integration into other circuits (microwave devices) and onto other substrate material (glass). The enabling element in the separation process is the high selectivity of etching between YBCO and other oxide materials. Thus, a thin layer of YBCO is used as the sacrificial layer in the structure, allowing rapid etchant ingress under the device structures and separation from the growth substrate. Initial demonstrations of microwave device tuning using a lifted-off STO layer is detailed.
