Abstract

In this work, we describe the technology and packaging of a quartz sensor with a thickness of 5 μm. The temperature dependence of the resonance frequency of quartz resonators can be used for thermal radiation sensors. The sensitive element in the form of a bowl or a cantilever is ion beam etched and must be able to vibrate freely. Impedance measurements show the vibration of the 5 μm thick resonators, however highly damped and with a low quality factor.
