Latest Patents
Hamasaki's latest patents focus on the fabrication method of superconducting quantum interference devices. One notable method involves constructing a DC-SQUID from short weak links with ultrafine wires. The process includes several steps: first, a niobium nitride film and a silicon nitride film are successively formed on a substrate. Next, oblique etching of these films is performed using a reactive ion etching process with a mixture of oxygen and CF.sub.4 gases to create an oblique edge. Finally, a barrier thin film and a counterelectrode of niobium are formed on this edge. The short weak links are fabricated using a field evaporation technique, where the counterelectrode material is field-evaporated to create conductive paths in the pinholes of the insulating thin film.
