| Abstract(in English) | We are developing integrated cryogenic current comparators (ICCCs). To obtain high accuracy, we have to optimize structures of ICCCs by repeating fabrication and testing of various ICCC structures. Moreover, because of integration of a lot of ICCC components such as winding coils, a superconductor shield, pick-up/input coils and a SQUID, a superconductor multilayer process including Josephson junctions is necessary. Due to these two reasons, development of ICCCs takes a long turn-around time. To shorten the turn-around time, we divided those ICCC components into two parts: each part is integrated on a single chip; one consists of a SQUID washer and the other consists of the remaining CCC core including an input coil. They are connected by using a flip-chip bonding technique. By this design scheme, we can concentrate on developing the CCC core, apart from the SQUID which is not necessary to be optimized, leading to a short turn-around time. In this scheme, however, the SQUID and the input coil should be carefully designed to have a sufficiently large coupling. We designed the input-coil and SQUID chips and evaluated the coupling coefficient. |
