Two different microbalance applications, based on temperature compensated t
hickness shear mode resonators (single rotated Y-cuts), were studied. In th
e first case, the film thickness growth during the sputter process was moni
tored. The measured frequency shift was in excellent agreement with the app
lied theory. In the second case, the selfcleaning by heating the crystal up
to 650 degreesC after contamination with particulates was demonstrated.
