Abstract
The method of constructing an air bridge on a substrate between spaced apart conductors on the substrate with the bridge spanning the distance between the conductors, by using PMGI to build a bridge pad on the substrate; using PMMA to build a bridge pattern over the pad with the ends of said conductors extending into said pattern; depositing titanium and gold over said pad within said pattern by directing the titanium and gold into said pattern onto said pad and conductor ends using relative motion between the substrate and the titanium and gold; and removing the PMGI and PMMA.
