Abstract:
An embedded piezoelectric resonator apparatus comprising:a flat piezoelectric plate with upper and lower surfaces with opposing top and bottom electrodes disposed thereon, respectively;a first and a second electrical conductor connected to the top and bottom electrodes, respectively;an upper substrate layer having an electronic circuit thereon and being substantially flat and having an orifice adapted to receive the first electrical conductor and an electrical trace disposed thereon for connecting the first electrical conductor to said electronic circuit; anda lower substrate having an orifice adapted to receive the second electrical conductor and an electrical trace for connecting to the second electrical conductor, the lower substrate having a pocket in one surface thereof facing said upper substrate;the upper substrate layer and lower substrate forming a substrate assembly, the pocket of the lower substrate defining a cavity within the substrate assembly adapted to contain the piezoelectric plate;the first electrical conductor extending upwardly from the top electrode of said piezoelectric plate and at least partially through the orifice in the upper substrate layer and electrically connecting to said electrical trace on the upper substrate layer;the second electrical conductor extending downwardly from the bottom electrode and at least partially through the orifice in the lower substrate and electrically connecting to an electrical trace on the lower substrate.
