Abstract

A new processing method for fabrication of narrow YBCO microbridges in ultrathin laser deposited films was developed. A 600 Å thick YBCO film on LaAlO₃ was covered by 200 Å of ZrO₂. A lift-off stencil made by electron beam lithography was produced and covered by a 500 Å ZrO₂ etch mask. The microbridges (down to 0.4 μm wide) were produced by ion milling. The 1μm wide microbridge showed T_c above 90 K and j_c above 10⁶ A/cm² at 77 K. This structure on a substrate with low dielectric loss is needed for ultrafast devices utilizing the electron heating effect.
