    摘要: A Micro ElectroMechanical System (MEMS) switch is provided. The MEMS switch includes a ground, a moving unit moveable according to a driving signal, for connecting the input to the output or disconnecting the input from the output, and an electrode unit arranged in the configuration of a protrusion formed on a portion of the round, to induce a leakage signal generated between the input and the output to move toward the ground.

    摘要: A resonator having a membrane formed of a piezoelectric layer sandwiched between first and second electrode is suspended above a cavity formed from the back surface of the support structure. In one embodiment, the cavity walls are substantially perpendicular to the back surface. In another embodiment, the first electrode is formed in the cavity such that it is electrically connected to an electrode on the back surface of the support structure. In yet another embodiment, the cavity is formed via an etch through via holes in the back surface of the support structure, which leads to greater flexibility in designing a method of manufacture while reducing the need for alignment relative to other designs.

    摘要: A method for fabricating subminiature, high-performance monolithic duplexer is disclosed. The method comprises depositing and patterning a lower electrode on an upper surface of an insulation layer on a substrate, so as to expose a first part of the insulation layer; depositing a piezoelectric layer on an upper surface of the exposed insulation layer and the lower electrode; depositing a metal on the upper part of the piezoelectric layer and patterning the metal to form a resonance part and a trimming inductor, wherein the lower electrode electrically couples the resonance part and the trimming inductor; fabricating air gap type FBARs (film bulk acoustic resonances) by forming a cavity by etching the substrate under the resonance part; and bonding a packaging substrate on the substrate, the packaging substrate having a phase shifting part which substantially prevents inflow of signal between the air gap type FBARs.

    摘要: An air-gap type film bulk acoustic resonator (FBAR) is created by securing two substrate parts, one providing a resonance structure and the other providing a separation structure, i.e., a cavity. When the two substrate parts are secured, the resonance structure is over the cavity, forming an air gap isolating the resonant structure from the support substrate. The FBAR may be used to form a duplexer, which includes a plurality of resonance structures, a corresponding plurality of cavities, and an isolation part formed between the cavities. The separate creation of the resonance structures and the cavities both simplifies processing and allows additional elements to be readily integrated in the cavities.
