The resonator component is suspended above a top surface of the base and is perpendicular to the base. The driving electrodes are coupling to side surfaces of the resonator component. The resonator component is formed in a shape of an essential regular polygon. The driving electrodes and the resonator component jointly form an electromechanical coupling system for converting capacitance into electrostatic force. Besides, a capacitive-type transverse extension acoustic wave silicon oscillator includes the transverse acoustic wave resonator and a method of fabricating the transverse acoustic wave resonator are also disclosed.

The cover includes a first metal ring to enclose the acoustic transducer unit. The base includes a second metal ring to press against the first metal ring in order to form a metal shielding area. First and second metal connecting paths are formed electrically connected to the metal shielding area and the acoustic transducer unit, respectively. Besides, two pairs of first and second surface mountable metal electrodes are electrically connected to the first and the second metal connecting paths, respectively. As a result, the package can be selectively double surface mountable to a user's circuit board via the metal electrodes of the base or the metal electrodes of the cover.
