Patent JP-H05175775-A (JP)
Title: Piezoelectric resonator
Inventor: YAMAZAKI DAISUKE
IPC: H03H3/04
Filed: 1991-12-25
Abstract: PURPOSE:To adjust easily and accurately the resonance frequency of the piezoelectric resonator employing a crystal vibrator with an electrode through chemical etching. CONSTITUTION:In the piezoelectric resonator employing a non-contact electrode type crystal vibrator, the crystal vibrator is chemically etched by using a hydrofluoric acid or the like to adjust a resonance frequency (f) to a prescribed value. For example, when the resonance frequency (f) is 10MHz, the thickness (t) is selected to be 160mum, and when the accuracy of the resonance frequency requires 10Hz, the accuracy DELTAt of the thickness is selected to be ¦DELTAt¦=1.6nm. In the case of the chemical etching, the concentration of etchant is diluted to decrease a rate of the etching. That is, the processing accuracy of the thickness is improved. As the etchant condition, in the case of 50%HF (23 deg.C+ or -0.5 deg.C), the etching rate is 105-110Hz/sec, the thickness results in 0.88nm/sec by taking the etching from both sides into account and the high processing accuracy is obtained. The accuracy of 110Hz is obtained by controlling the etching time with the accuracy of nearly 1sec.
