Abstract:
1. A method comprising: forming at least one piezoelectric filter structure comprising a plurality of electrodes formed to be in contact with at least one piezoelectric substrate; and forming a micro-electro-mechanical structure (MEMS) comprising a MEMS beam in which, upon actuation, the MEMS beam will turn on the at least one piezoelectric filter structure by interleaving electrodes in contact with the piezoelectric substrate or sandwiching the at least one piezoelectric substrate between the electrodes; depositing a sacrificial material over the insulator layer; forming the MEMS beam on the sacrificial material; forming the at least one piezoelectric substrate on the MEMS beam; forming additional sacrificial material on the least one piezoelectric substrate and the MEMS beam: forming a second insulator layer on the MEMS beam and the least one piezoelectric substrate; venting the sacrificial material and the additional sacrificial material through at least one vent hole to form an upper cavity and a lower cavity about the MEMS beam and the least one piezoelectric substrate; and closing the at least one vent hole with material.
