  • Quartz Tuning-Fork Resonators and Production Method
    Publication number: 20060196845
    Abstract: Methods and apparatus for producing crystalline Quartz tuning-fork resonators using a deep reactive ion etching process. The resonators have an outline formed by a method including masking a substrate with a metal mask. The metal mask being resistant to reactive ion etching and conforming to the outline. The resulting plasma etched resonators are strong and have a high degree of symmetry, which substantially reduces common critical performance errors occurring in accelerometers, pressure sensors, tilt meters, scales, and rate gyroscopes.
