Latest Patents

Mori's latest patents include a "DC-powered Josephson integrated circuit" and a "Method of forming Josephson junction devices." The DC-powered integrated circuit features a design that incorporates multiple magnetic flux coupling type Josephson elements. This innovative circuit connects first and second Josephson elements in series to create a first element series circuit, while third and fourth elements form a second series circuit. These circuits are then connected in series to form a huffle circuit, which includes a load inductance, three resistors, and a DC current source.

The second patent outlines a method for producing Josephson junction devices using thin films of superconducting materials such as niobium and niobium nitride. This method involves forming a base electrode layer, a tunnel barrier layer, and a counterelectrode layer on a substrate. The process utilizes a resist pattern as a mask for dry etching, followed by a plasma ashing process to create a terrace-shaped portion at the edges and corners of the counterelectrode pattern. This meticulous approach ensures the production of high-quality Josephson junction devices.
