    Abstract: A method for forming macropores in a substrate is disclosed. On a substrate a pattern of submicron features is formed. This pattern is covered with a layer, which is preferably selectively removable with respect to the substrate and the submicron features. This cover layer is removed until the submicron features are exposed. The submicron features are then etched selectively to the cover layer, thereby creating a pattern of submicron openings in this cover layer. The patterned cover layer is used as a hardmask to etch macropores in the substrate.

    Abstract: Described is a method for manufacturing a micromechanical sensor element and a micromechanical sensor element manufactured in particular using such a method which has a hollow space or a cavity and a membrane for detecting a physical variable. Different method steps are performed for manufacturing the sensor element, among other things, a structured etch mask having a plurality of holes or apertures being applied on a semiconductor substrate. Moreover, an etch process is used to create depressions in the semiconductor substrate beneath the holes in the structured etch mask. Anodization of the semiconductor material is subsequently carried out, the anodization taking place preferably starting from the created depressions in the semiconductor substrate. Due to this process, porous areas are created beneath the depressions, a lattice-like structure made of untreated, i.e., non-anodized, substrate material remaining between the porous areas and the depressions. This lattice-like structure extends preferably from the surface of the semiconductor into the depth. The etch mask for creating the depressions may be removed, optionally prior to or subsequent to the anodization. A temperature treatment is carried out for creating the hollow space and the membrane in the semiconductor substrate which forms the sensor element. During this process, the hollow space is created from the at least one area that has been rendered porous beneath a depression and the membrane above the hollow space is created from the lattice-like structure by rearranging the semiconductor material.

    Abstract: In a method for producing a diaphragm sensor array having a semiconductor material substrate on which a plurality of planar diaphragm regions is arranged as a carrier layer for sensor elements, the planar diaphragm regions are thermally decoupled from one another by crosspieces made of a material having clearly better heat conductive properties compared to the diaphragm regions and the lateral surroundings of the crosspieces. Masking for a subsequent step for producing porous semiconductor material is applied at the locations of the semiconductor material substrate at which the crosspieces for the thermal decoupling are formed, and the semiconductor regions not protected by the masking are rendered porous and the diaphragm regions are produced thereupon. Instead of using porous silicon, a plasma etching process may be performed from the backside of a semiconductor material substrate. In particular, high integration densities of diaphragm sensors may be achieved with both methods. A diaphragm sensor array is produced by one of the methods.
