Low temperature Bi-CMOS compatible process for MEMS RF resonators and filters
Leena Paivikki Buchwalter,Kevin K. Chan,Timothy J. Dalton,Christopher V. Jahnes,Jennifer L. Lund,Kevin S. Petrarca,James L. Speidell,James F. Ziegler +7 more
TL;DR: In this article, a method of formation of a microelectromechanical system (MEMS) resonator or filter which is compatible with integration with any analog, digital, or mixed-signal integrated circuit (IC) process, after or concurrently with the formation of the metal interconnect layers in those processes, by virtue of its materials of composition, processing steps, and temperature of fabrication is presented.
