| Outline of Final Research Achievements |
We investigated adiabatic superconductor logic, or AQFP logic, using niobium nitride (NbN) to achieve superconductor integrated circuits that can operate at higher temperature than 4 K. We designed NbN-AQFP logic gates using the NbN integrated-circuit fabrication process provided by the National Institute of Information and Communications Technology (NICT). We designed the mask layout of a test circuit that includes basic NbN-AQFP logic gates and fabricated it using the NICT process. We also evaluated the operational stability and energy dissipation of NbN-AQFP gates. Our results indicate the advantage of NbN-AQFP gates: small circuit area; high operational stability; small energy dissipation.
