摘要:
A method provides time-dependent automatic acclimatization of at least one parameter of a hearing device, for example the volume, to a predeterminable target. In the method the speed of the automatic acclimatization is influenced by parameter changes made by a wearer of the hearing device himself. Advantageously this makes it possible to address the individual familiarizing phase and requirements of the wearer of the hearing device and finally to set an optimum parameter value.

A method for producing a solar cell from a silicon wafer, including the following process steps: A) texturizing one side of the silicon substrate (1) for improving the absorption or removing saw damage on one side of the silicon substrate (1); B) generating an emitter area (2) on one side of the silicon substrate (1) by diffusing in a doping material for forming a pn transition; C) removing a glass layer which comprises the doping material; D) applying a masking layer (3) which is a dielectric layer; E) removing one part of the material of the silicon substrate (1); F) applying metal structures (5, 6) for electrically contacting the solar cell. It is significant that thermal oxidation is performed between the process steps E and F for forming an oxide layer (4) and that the masking layer (3) and the oxide layer (4) remain on the silicon substrate (1) in the subsequent process steps.

A method for local contacting and local doping of a semiconductor layer including the following process steps: A) Generation of a layer structure on the semiconductor layer through i) application of at least one intermediate layer on one side of the semiconductor layer, and ii) application of at least one metal layer onto the intermediate layer last applied in step i), wherein the metal layer at least partly covers the last applied intermediate layer, B) Local heating of the layer structure in such a manner that in a local region a short-time melt-mixture of at least partial regions of at least the layers: metal layer, intermediate layer and semiconductor layer, forms. After solidification of the melt-mixture, a contacting is created between metal layer and semiconductor layer. It is essential that in step A) i) at least one intermediate layer designed as dopant layer is applied, which contains a dopant wherein the dopant has a greater solubility in the semiconductor layer than the metal of the metal layer.

The invention relates to a method for the production of a semiconductor component having at least one optically reflective surface in which a silicon wafer, which has an etchable dielectric layer at least in regions on at least one of its surfaces, is provided with a silicon-containing masking layer in order to screen against fluid media. In addition a layer comprising aluminium is deposited on the masking layer and subsequently a thermal treatment of the semiconductor component is undertaken, the result being dissolving of the silicon in the aluminium. Furthermore, the invention relates to a corresponding semiconductor component made of a silicon wafer having at least one optically reflective surface. Semiconductor components of this type are used in particular as solar cells.
