Abstract: The resonator comprises a first electrode (E1), a second electrode (E2) and a piezoelectric layer (P) arranged between the above. A first acoustic compression layer (V1) is arranged between the piezoelectric layer (E1) and the first electrode (E1) with a higher acoustic impedance than the first electrode (E1).

Abstract: An acoustic mirror is described which is formed of at least one first insulating layer, a first metal layer disposed thereon, a second insulating layer disposed thereon and a second metal layer disposed thereon. An auxiliary layer is produced on the first insulating layer whereby a recess extending as far as the first insulating layer is created therein. The first metal layer is substantially deposited and removed by chemical/mechanical polishing until the parts of the first metal layer disposed outside the recess are no longer present. The second metal layer is also produced in a recess with the aid of chemical/mechanical polishing. More than two insulating layers and two metal layers can be provided. The first metal layer and the second metal layer can be produced in the same recess.

Abstract: A temperature control apparatus for single wafer etching tools comprising a cathode electrode, an isolation layer, and chuck means, respectfully, which are vertically stacked to support a wafer to be etched. A layer of thermoelectric elements is disposed between the isolation layer and the chuck means. The layer of thermoelectric elements comprises a center area closed loop of connected Peltier elements and an outer area closed loop of connected Peltier elements. The center area closed loop is coupled to a power source and is arranged to correspond to the center area of the wafer. The outer area closed loop is coupled to a power source and is arranged to correspond to the outer area of the wafer. Accordingly, the temperatures associated with each of the specific areas of the wafer are individually controlled by one of the closed loops.

Abstract: In a method for manufacturing a piezoelectric oscillating circuit in thin film technology, wherein the oscillating circuit includes a predetermined natural frequency and a plurality of layers, first of all at least a first layer of the piezoelectric oscillating circuit is generated. Subsequently, by processing the first layer a frequency correction is performed. Subsequently, at least a second layer of the piezoelectric oscillating circuit is generated and processed for performing a second frequency correction.

Abstract: A bulk acoustic wave (BAW) filter arrangement has a BAW-filter (100) with a first BAW-resonator (R1) and a second BAW-resonator (R3) formed on a substrate. The first BAW-resonator is placed in a series branch of the BAW-filter, while the second BAW-resonator is placed in a parallel branch of the same filter and has an inductive component whose inductance is selected in order to adjust a given property of the second BAW-resonator. A housing (102) accommodates the substrate of the BAW-filter and the inductive component of the second BAW-resonator is formed by an electrical connection (116) between the second BAW-resonator and a grounding pad (110) in the housing.

Abstract: The invention relates to a micromechanical sensor and to a corresponding production method that includes the following steps: a) preparing a doped semiconductor wafer; b) applying an epitaxial layer that is doped in such a way that a jump in the charge carrier density in the interface between the semiconductor wafer and the epitaxial layer occurs; c) optionally etching ventilation holes traversing the epitaxial layer and optionally filling the ventilation holes with a sacrificial material; d) depositing at least one sacrificial layer, at least one spacing layer, a membrane and optionally a semiconductor circuit on the top side of the epitaxial layer using a technology known per se, wherein the semiconductor circuit may be applied after the membrane is formed or while depositing the layers required to form the membrane; e) etching a hole on the back part of the sensor, wherein the etching method is selected in such a way that etching advances in the direction of the top side and ceases in the interference between the wafer and the epitaxial layer by changing charge carrier concentration. The invention also relates to the utilization of the micromechanical sensor in pressure sensors or microphones.
