• A new process was developed for preparing four superconducting field effect transistors (SuFET's) on a substrate. This process yielded the gate structure of YBa2Cu3O7- x/SrTiO3/YBa2Cu3O7- x (YBCO/STO/YBCO) and the contact structure of buried YBCO electrodes. The average T c of the YBCO (100 nm)/STO (200 nm)/ YBCO (5 nm) structures was 49.7 K and the I–V characteristics of gate STO were symmetric. The temperature dependence of transconductance was larger compared with other SuFET's reported to date. Furthermore, we confirmed the operation of all the SuFET's on one substrate and two adjacent SuFET's connected in series. This device fabrication process also led to improved T c values of ultrathin YBCO channels.
