    摘要: A method and a plasma system are provided for anisotropically etching structures into a substrate positioned in an etching chamber, e.g., structures defined using an etching mask in a silicon substrate, using a plasma. For this purpose, the etching chamber is supplied at least intermittently with an etching gas and at least intermittently with a passivation gas, the passivation gas being supplied to the etching chamber in cycles having a time period between 0.05 second and 1 second. In the plasma system, in addition to a plasma source, via which the plasma acting on the substrate may be produced, an arrangement is provided for at least temporary supply of the etching gas and at least temporary supply of the passivation gas to the etching chamber, which arrangement is designed in such a way that the passivation gas may be supplied to the etching chamber in cycles having a time period between 0.05 second and 1 second.

    摘要: A holding device including a holding element, on which a substrate is electrostatically fixed, positioned on a substrate electrode. In one configuration, a load body on the substrate electrode presses the holding element onto it, and is connected via a clamping device, which presses the former onto the substrate electrode, with a base, which supports the substrate electrode, the load body and the base being electrically insulated from the substrate electrode. In another configuration, the side of the holding element faces the substrate as an electrically insulating ferroelectric or piezoelectric material. Another configuration includes a device via which a liquid convection medium is feedable into a space formed by the holding element and substrate or is removable from there again. A method for supplying heat or dissipating heat from the back of a substrate to which heat is applied from the front, and which is held by the holding device.

    摘要: A component having a robust, but acoustically sensitive microphone structure is provided and a simple and cost-effective method for its production. This microphone structure includes an acoustically active diaphragm, which functions as deflectable electrode of a microphone capacitor, a stationary, acoustically permeable counter element, which functions as counter electrode of the microphone capacitor, and an arrangement for detecting and analyzing the capacitance changes of the microphone capacitor. The diaphragm is realized in a diaphragm layer above the semiconductor substrate of the component and covers a sound opening in the substrate rear. The counter element is developed in a further layer above the diaphragm. This further layer generally extends across the entire component surface and compensates level differences, so that the entire component surface is largely planar according to this additional layer. This allows a foil to be applied on the layer configuration of the microphone structures exposed in the wafer composite, which makes it possible to dice up the components in a standard sawing process.

    摘要: A method for producing micromechanical patterns having a relief-like sidewall outline shape or an angle of inclination that is able to be set, the micromechanical patterns being etched out of a SiGe mixed semiconductor layer that is present on or deposited on a silicon semiconductor substrate, by dry chemical etching of the SiGe mixed semiconductor layer; the sidewall outline shape of the micromechanical pattern being developed by varying the germanium proportion in the SiGe mixed semiconductor layer that is to be etched; a greater germanium proportion being present in regions that are to be etched more strongly; the variation in the germanium proportion in the SiGe mixed semiconductor layer being set by a method selected from the group including depositing a SiGe mixed semiconductor layer having varying germanium content, introducing germanium into a silicon semiconductor layer or a SiGe mixed semiconductor layer, introducing silicon into a germanium layer or an SiGe mixed semiconductor layer and/or by thermal oxidation of a SiGe mixed semiconductor layer.
