An exemplary capacitor includes a first plate formed on a glass substrate, a second plate, and a dielectric layer. No organic bonding agent is used between the first plate and the glass substrate, and the dielectric layer can be an intrinsic semiconductor. A extrinsic semiconductor layer that is heavily doped contacts the dielectric layer. The dielectric and extrinsic semiconductor layers are sandwiched between the first and second plates. An intermetallic layer is formed between the first plate and the dielectric layer. The intermetallic layer is thermo compression bonded to the first plate and the dielectric layer.

摘要： A method and apparatus for a piezoelectric resonator having combined thickness and width vibrational modes are disclosed. A piezoelectric resonator may include a piezoelectric substrate and a first electrode coupled to a first surface of the piezoelectric substrate. The piezoelectric resonator may further include a second electrode coupled to a second surface of the piezoelectric substrate, where the first surface and the second surface are substantially parallel and define a thickness dimension of the piezoelectric substrate. Furthermore, the thickness dimension and the width dimension of the piezoelectric substrate are configured to produce a resonance from a coherent combination of a thickness vibrational mode and a width vibrational mode when an excitation signal is applied to the electrodes.

摘要： This disclosure provides implementations of electromechanical systems resonator structures, devices, apparatus, systems, and related processes. A resonator structure generally includes a first conductive layer with an input electrode, an output electrode, and a ground electrode. The ground electrode is disposed between the input electrode and the output electrode. In some implementations, the second conductive layer includes an input electrode, an output electrode, and a ground electrode. In some other implementations, a second conductive layer includes a pair of ground electrodes and a signal electrode in the form of an input or output electrode disposed between the ground electrodes. A piezoelectric layer is disposed between the first conductive layer and the second conductive layer. Sub-resonators can be defined in different regions of the structure, such that the piezoelectric layer is capable of moving to produce an output signal having frequencies at a first resonant frequency and a second resonant frequency.

摘要： Bridge structures provide a surface on which to form interconnections to components through through-hole vias. The bridge structures at least partially, and preferably fully, span the gap between two wafers, and, more specifically, between a through-hole via in one wafer and a corresponding component on the other wafer. Bridge structure may be formed on the wafer having the through-hole via and/or the wafer having the component.
