Abstract
Abstract A semiconductor device having an air bridge wiring structure comprising a first layer of conductors disposed on a semiconductor substrate, a plurality of bridges posts disposed on widened portions of the first layer of conductors, and bridge plates disposed straddling a plurality of bridge posts, the widened portions of the first layer of conductors being disposed at positions which are not in straight lines but are shifted with respect to each other.
