| Abstract: | Film bulk acoustic resonators (FBAR) and BAW filters have many advantages, such as high operation frequency, being small in size and easy for fabrication and integration, and so on. It becomes fit for modern communication applications. The properties and fabrications of some major materials for FBAR such as AlN, ZnO, PZT are introduced systematically, and the structures, devices design and applications of BAW filters are discussed as well. |
