Abstract:

This report describes a prototype on-chip electrical transformer that was developed using high-transition-temperature superconducting films. Two approaches for making high-T. films were pursued melt-processing of thick films and sputter deposition of thin films. It is concluded that further optimization of production procedures particularly for YBa2CU307 thin films will lead to films with much higher critical currents. Practical microelectronic transformers and other inductive devices will require such high-quality films as well as the ability to deposit multiple superconducting and insulating layers.
