Manufacturing film bulk acoustic resonator filters. |
摘要 |
A film bulk acoustic resonator filter (10) may be formed with a plurality of interconnected series and shunt film bulk acoustic resonators (38) formed on the same membrane (35). Each of the film bulk acoustic resonators (38) may be formed from a common lower conductive layer which is defined to form the bottom electrode (32) of each film bulk acoustic resonator (38). A common top conductive layer may be defined to form each top electrode (36) of each film bulk acoustic resonator (38). A common piezoelectric film layer (34), that may or may not be patterned, forms a continuous or discontinuous film. <IMAGE> |
