Abstract : The resonant frequencies of a piezoelectric resonator are adjusted either before sealing the resonator into an enclosure or after sealing the resonator into an enclosure or both before and after sealing the resonator into an enclosure. The method makes use of radiation to polymerize a polymerizable gas that has been introduced into the enclosure that houses the resonator. The resulting polymer that deposits on the resonator adjusts the resonant frequencies of the resonator from undesired frequencies to desired frequencies. (Author)
