ULVAC Piezo-MEMS Solution Technology

Piezoelectric thin films have been integrated with advanced silicon-based microfabrication methods in the formation of both sensors and actuators such as gyro/acceleration sensor, microphone, piezoelectric micro-machined ultrasonic transducer (pMUT), micro-actuator and Film Bulk Acoustic Resonator (FBAR). These films have become recognized as key enabling technologies for “Smartphones”, “Wearable devices” and “Autonomous car” which are becoming one of the most important parts of the “Smart infrastructure” of a modern “Smart Society”. ULVAC will introduce the newly developed mass production technology for Piezo-MEMS.

ULVAC Product Information

For MEMS application ULVAC has developed systems dedicated to MEMS sensors, actuators, switches, lab-on-chip and micromirror manufacturing. This equipment range includes sputtering and etching for piezo electric materials like PZT, AlN and ScAlN, glass and metal etching, thick resist ashing, resist and polymer removal within trench structures, and others.

Piezoelectric materials can be used to further miniaturize a range of devices, including inertial sensors, tuneable RF devices, inkjet print heads, micromirrors, microphones, autofocus lenses and others. The integration of thin film deposition directly on CMOS-processed wafers is key for highly-integrated devices. ULVAC has developed high-volume processing sputtering method that allows sub 500°C processing temperatures, is configured to pole the piezoelectric crystals during the deposition process and is compatible with other CMOS processes.
