The 2D cuprate superconductor BSCCO, promises upon integration with CMOS electronics, on-chip high temperature superconducting single photon detectors or quantum interference device (SQUID). Unfortunately, its properties degrade quickly if exposed to elevated temperatures, solvents, oxygen or water. Here we present Hall devices with a record thin film Tc of 91 K, which is identical to the bulk value of the crystal. Electrical contacts were established through transfer-printable circuits embedded in SiNx nanomembranes. The membrane incapsulates the material shielding it from the environment, while via contacts are used to form the electrical contacts.
