Patent ID: 8735326

Claim:
A method of forming a superconductor circuit, the method comprising: depositing a protective barrier layer over a superconducting material layer; curing the protective barrier layer; depositing a photoresist material layer over the protective barrier layer; irradiating and developing the photoresist material layer to form an opening pattern in the photoresist material layer; etching the protective barrier layer to form openings in the protective barrier layer based on the opening pattern; etching the superconductor material layer based on the openings in the protective barrier layer to form openings in the superconductor material layer that define a first set superconductor material raised portions; stripping the photoresist material layer and the protective barrier layer; and wherein the superconducting material layer is a first superconducting material layer that overlies a dielectric layer overlying a second superconducting material layer that together form a tri-layer.
