    We describe a wet etch process for patterning insulators suitable for multilayer epitaxial highTc superconductor‐insulator‐superconductor structures down to micronmeter‐scale dimensions. A solution of 7% HF in water gives convenient etch rates for SrTiO3 and MgO insulators (about Å/min for single crystals), and easily stops on thin high Tc superconducting layers, due to the high. Further, with a growing demand for electronics having miraculous characteristics (low noise, low loss, low dissipation, less weight, high resolution, high speed, high frequency, etc), use of electronic and superconductivity properties of materials—together known as ‘superconducting electronics’ or ‘electronics with superconductors.

    A solution of 7% HF in water gives convenient etch rates for SrTiO 3 and MgO insulators (about Å/min for single crystals), and easily stops on thin high T c superconducting layers, due to the high selectivity of this etchant between these insulators and the cuprate superconductors. Low pressure metal-organic chemical vapor deposition has been used to grow dielectric thin films of the tetragonal perovskites LaSrGaO 4 and PrSrGaO 4 on () LaAlO 3 using the volatile metal sources Pr(dpm) 3, La(hfa) 3 tri, Ga(dpm) 3, and Sr(hfa) 2 tet (dpm = dipivaloylmethanate, hfa = hexafluoroacetylacetonate, tet = tetraglyme, and tri = triglyme).

Electronics based on high transition temperature superconductive thin film materials is presently viable in some important niches, particularly in passive microwave circuits.

Various processes for fabrication of superconducting film are known such as evaporation, sputtering, ion cluster beam, chemical vapor deposition, etc. Sputtering is attractive because of its good controllability of composition and reproducibility among these processes.
