Lange coupler system and method

A system and method for the fabrication of high reliability high performance Lange couplers (optionally including capacitors, inductors, multi-layer interconnects, and resistors) on various thin film hybrid substrate surfaces is disclosed. The disclosed Lange coupler method first employs a thin metal layer deposited and patterned on the substrate. This thin patterned layer is used to provide both lower electrodes for capacitor structures and interconnects between upper electrode components. Next, a dielectric layer is deposited over the thin patterned layer and the dielectric layer is patterned to open contact holes to the thin patterned layer. The upper electrode layers are then deposited and patterned on top of the dielectric. The resulting Lange coupler structure has significantly improved electrical performance over the prior art, while incorporating overall structural integrity superior to that of the prior art.
