Abstract(in English) | We have fabricated single-flux-quantum (SFQ) logic circuits operating at around 10 K by using NbN film with a critical temperature of around 16 K. The circuits were fabricated on 2 inch Si substrate based on NbN/AlN/NbN tunnel junctions with the critical current variation less than ±5% in the 976JJ array. We confirmed the correct operation of dc/SFQ and SFQ/dc converters up to 9.8 K. We also confirmed the correct operation of elementary cells such as a Confluence buffer and a T-Flip-Flop at 8.5 K. As the largest scale integrated circuit, an 8 bit shift resister with the 105 Josephson junction was successfully operated at 8.5 K. |
