Abstract
A handle wafer has a cavity coated with a dielectric. A device wafer is bonded to the handle wafer. Metal lines, devices or circuits fabricated on device layer overlay the cavity in the handle wafer thus reducing parasitic capacitances to the handle wafer and crosstalk through the handle wafer. This constitutes a rugged air bridge structure capable of being passivated and/or being placed in plastic packages.
