Configuring all wiring dimensions for a high speed, low temperature integrated circuit on the same level on an insulated ground plane provides good transmission line characteristics; where necessary, insulated jumpers are provided as crossovers. The net result has better transmission line characteristics than a package having a separate metallization level for each dimension. In package wiring where high speed and high density are required, it is important to control the impedance of the transmission lines with a good wiring yield. In Josephson packaging, where thin film levels are solely used for wiring, these requirements are particularly critical.
