Title: Excision method for electrode
Inventor: KURISU TORU
IPC: B23K26/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To excise an electrode without deteriorating Q of a dielectric body resonator etc., and without using many equipment by including a first process to excise the electrode formed on a dielectric body with a laser beam and a second process to excise the degeneration layer generated at a section which has been cut with a laser beam, with a short pulse laser beam. SOLUTION: In a first process, input/output electrodes are irradiated with a second higher harmonic YAG laser beam so as to form an insulated part. The degenerated layer, in which a dielectric body and an electrode melted with laser beam heat are solidified to be of low resistance, and the degeneration layer, in which the dielectric body is rapidly cooled to be a semiconductor, are generated to a laser beam irradiated section. When these degeneration layers are produced, the property of a dielectric resonator 10 with low Q is deteriorated. In a second process, the section of the degenerated layer is irradiated with a short pulse laser beam, because the degenerated layer is excised without imparting a heat load to the dielectric resonator 10, the dielectric resonator 10 having reduced Q deterioration is obtained.  The dielectric resonator 10 is held by a holder 20 rotatable with a rotary shaft 21 and position-adjusted by adjusting the direction of the holder 20.
