    摘要: A film bulk acoustic resonator filter may be formed with a plurality of interconnected series and shunt film bulk acoustic resonators formed on the same membrane. Each of the film bulk acoustic resonators may be formed from a common lower conductive layer which is defined to form the bottom electrode of each film bulk acoustic resonator. A common top conductive layer may be defined to form each top electrode of each film bulk acoustic resonator. A common piezoelectric film layer, that may or may not be patterned, forms a continuous or discontinuous film.

    摘要: An apparatus and method to provide a tapered electrode in an acoustic resonator. A piezoelectric (PZ) layer, such as Aluminum Nitride (AIN), is formed over a bottom electrode having a tapered end. A top electrode is positioned on the PZ layer. The tapered end of the bottom electrode creates a mild topography to the under layer of the PZ material to prevent cracking in the PZ layer. The tapered end also decreases acoustic losses in the acoustic resonator because the PZ grains are highly oriented. In one embodiment, the acoustic resonator is a film bulk acoustic resonator (FBAR).

    摘要: A diaphragm includes a substrate having a hole and a sheet of material formed on the substrate and covering the hole. The sheet of material includes one or more corrugations that are substantially free of defects. A method of forming the diaphragm includes forming a corrugated surface free of stringers on the substrate, forming a layer of material on the corrugated surface, and processing the substrate to form the diaphragm including the layer of material.
