    摘要: The present disclosure concerns an emitter package for a photoacoustic sensor, the emitter package comprising a MEMS infrared radiation source for emitting pulsed infrared radiation in a first wavelength range. The MEMS infrared radiation source may be arranged on a substrate. The emitter package may further comprise a rigid wall structure being arranged on the substrate and laterally surrounding a periphery of the MEMS infrared radiation source. The emitter package may further comprise a lid structure being attached to the rigid wall structure, the lid structure comprising a filter structure for filtering the infrared radiation emitted from the MEMS infrared radiation source and for providing a filtered infrared radiation in a reduced second wavelength range.

    摘要: A method for manufacturing a micromechanical environmental barrier chip includes providing a substrate having a first surface and an opposite second surface, depositing a material layer having a different etch characteristic than the substrate onto the first surface, creating a microstructured micromechanical environmental barrier structure on top of the material layer by applying a microstructuring process, applying an anisotropic etching process comprising at least one etching step for anisotropically etching from the second surface towards the first surface to create at least a cavity underneath the micromechanical environmental barrier structure, the cavity extending between the second surface and the material layer, and removing the material layer underneath the micromechanical environmental barrier structure to expose the environmental barrier structure.

    摘要: A device for debonding a structure from a main surface region of a carrier includes a tape for laminating to the structure, a first holder and a second holder for spanning the tape and to keep a tension of the tape. The second holder can be movable into a lifted position vertically offset to the main surface region of the carrier. The device can also include a deflecting-element for providing a deflection-line between the first holder and the second holder for deflecting the tape in response to moving the second holder into the lifted position. The deflecting-element can be moveable parallel to the carrier for moving the deflection-line parallel to the carrier and for debonding the structure, laminated to the tape, from the carrier.
