Electric device market needs

Electric device performance typically deteriorates with miniaturization. The market needs electric devices that offer the same high performance even after they are downsized.
Epson's competitive advantage lies in QMEMS, crystal devices that meet these market requirements.

What is QMEMS?

QMEMS is a combination of 'Quartz', a crystal material with excellent characteristics such as high stability and high precision, and "MEMS" (a microfabrication technology). To a semiconductor MEMS material, we apply precision microprocessing based on quartz material to create a quartz device that we call 'QMEMS' which offers high performance in a compact package.

The QMEMS lineup

Applying our photolithography processing technology, proven in over 30 years of tuning-fork crystal unit production, we provide a range of subminiature, high-precision, high stability quartz devices.
