Abstract
A method for manufacturing a piezoelectric component in which a resonating portion on a piezoelectric substrate is provided with a deposit that is sensitive to radiation in a range of wavelengths from 350 to 2000 nm so as to have portions thereof trimmed away to form indentations therein without burning the deposit to avoid generating heat that is injurious to the piezoelectric component and substrate. A laser beam in the frequency range of 350 to 2000 nm is then caused to impinge on the deposit to cause the formation of trimmed indentations without substrate damaging heat in a controlled manner to adjust the resonance frequency of the piezoelectric component.
