The degradation of an ultrathin YBCO layer under SrTiO/sub 3/ due to oxygen deficiency poses a fundamental problem in growing a bilayer which may be patterned into a superconducting FET. Annealing between depositions while growing the bilayer can help increase the T/sub c/ of the YBCO while retaining acceptable quality of the SrTiO/sub 3/. This study found T/sub c/ in the range of 60-80 K for a 4 unit-cell thick YBCO film under SrTiO/sub 3/.>
