Abstract(in English) | Moats are designed in different shapes and arranged in different patterns to determine how they affect the I-V characteristics of 1000 serially connected SQUID test circuits. Results show that surrounding the Josephson devices with narrow rectangular moats is very effective in preventing magnetic flux from being trapped, provided that the external magnetic flux within the moats is less than one flux quantum Φ_0. A 4-Kbit RAM, designed with these moats, is operated with an almost full bit yield of 99.8%, without any detrapping. This high bit yield is obtained even with a magnetic field as large as several milli-Gauss. |
