Enabling Fabrication Solutions for Advanced Piezoelectric MEMS
Capacitive MEMS technology has been enabling innovative functionality in electronic devices for over three decades. Huge advances in these technologies have continually delivered improved performance, but as the technology matures, the industry is looking for new opportunities to drive advances. MEMS solutions based on piezoelectric materials represent a potential technology inflection for MEMS. Of course, piezoelectric MEMS are not new. MEMS RF filters based upon AlN and AlScN films are some of the most successful MEMS devices deployed today. But even for these devices, as the level of Sc doping increases, so do the challenges in fabrication. Indeed, similar challenges are observed for MEMS devices based on other piezoelectric materials such as PZT. In this presentation, we will discuss these fabrication challenges and the work that Lam is doing to enable this exciting branch of MEMS technology.
