    Abstract: A method for fabricating a microstructure is to form at least one insulation layer including a micro-electro-mechanical structure therein over an upper surface of a silicon substrate. The micro-electro-mechanical structure includes at least one microstructure and a metal sacrificial structure that are independent with each other. In the metal sacrificial structure are formed a plurality of metal layers and a plurality of metal via layers connected to the respective metal layers. A barrier layer is formed over an upper surface of the insulation layer, and an etching stop layer is subsequently formed over a lower surface of the silicon substrate. An etching operation is carried out from the lower surface of the silicon substrate to form a space corresponding to the micro-electro-mechanical structure, and then the metal sacrificial structure is etched, thus achieving a microstructure suspension.

    Abstract: A method is proposed which will enable cavities having optically transparent walls to be produced simply and cost-effectively in a component by using standard methods of microsystems technology. For this purpose, a silicon region is first produced, which is surrounded on all sides by at least one optically transparent cladding layer. At least one opening is then produced in the cladding layer. Over this opening, the silicon surrounded by the cladding layer is dissolved out, forming a cavity within the cladding layer. In this context, the cladding layer acts as an etch barrier layer.
