    Abstract: A BAW device includes a semiconductor substrate with a surface region, an insulating layer formed on the surface region and a piezoelectric layer sandwiched by a first and second electrode, wherein the second electrode is formed on the insulating layer. The surface region is performed such that a voltage dependence of a capacitance between the substrate and the second electrode is substantially suppressed.

    Abstract: One embodiment of the present invention relates to method for the concurrent deposition of multiple different crystalline structures on a semiconductor body utilizing in-situ differential epitaxy. In one embodiment of the present invention a preparation surface is formed, resulting in two distinct crystalline regions, a monocrystalline silicon substrate region and an isolating layer region. A monocrystalline silicon layer and an amorphous silicon layer are concurrently formed directly onto the preparation surface in the monocrystalline silicon substrate region and the isolating layer region, respectively. Deposition comprises the formation of two or more sub-layers. The process parameters can be varied for each individual sub-layer to optimize deposition characteristics.

    Abstract: In the inventive method for the wet-chemical removal of a sacrificial material in a material structure, there is first provided the material structure, wherein the material structure has a treatment region with the sacrificial material accessible through an opening. Subsequently, the sacrificial material is brought into contact with a wet-chemical treatment agent through the opening for the removal of the sacrificial material, wherein a mechanical vibration is generated in the wet-chemical treatment agent or in the wet-chemical treatment agent and the material structure during the contacting of the sacrificial material with the wet-chemical treatment agent.
