    Abstract: In accordance with an embodiment of the present invention, a method of forming a semiconductor device includes forming a sacrificial layer over a first surface of a workpiece having the first surface and an opposite second surface. A membrane is formed over the sacrificial layer. A through hole is etched through the workpiece from the second surface to expose a surface of the sacrificial layer. At least a portion of the sacrificial layer is removed from the second surface to form a cavity under the membrane. The cavity is aligned with the membrane.

    Abstract: According to an embodiment, a micro-fabricated test structure includes a structure mechanically coupled between two rigid anchors and disposed above a substrate. The structure is released from the substrate and includes a test layer mechanically coupled between the two rigid anchors. The test layer includes a first region having a first cross-sectional area and a constricted region having a second cross-sectional area smaller than the first cross-sectional area. The structure also includes a first tensile stressed layer disposed on a surface of the test layer adjacent the first region.

    Abstract: A photoacoustic gas sensor device for analyzing gas includes an emitter module and a pressure-sensitive module. The emitter module is arranged on a carrier substrate and emits light pulses. The pressure-sensitive module is arranged on the carrier substrate within a reference gas volume. The reference gas volume is separated from a volume intended to be filled with a gas to be analyzed. Further, the pressure-sensitive module generates a sensor signal indicating information on an acoustic wave caused by light pulses emitted by the emitter module interacting with a reference gas within the reference gas volume. Additionally, the emitter module is arranged so that light pulses emitted by the emitter module reach the reference gas volume after crossing the volume intended to be filled with the gas to be analyzed.

    Abstract: An apparatus for in-situ calibration of a photoacoustic sensor includes a measurement device configured to measure an electric signal at an IR emitter of the photoacoustic sensor, wherein the IR emitter generates an electromagnetic spectrum based on the electric signal; and a calibration unit including processing circuitry, configured to compare the electric signal with a comparison value to generate a comparison result used as calibration information. When performing the in-situ calibration, the calibration unit is configured to adjust the electric signal based on the calibration information, or the calibration unit is configured to process an output signal of the photoacoustic sensor based on the calibration information to obtain an adjusted output signal of the photoacoustic sensor.
