摘要:
A method for manufacturing a semiconductor structure is provided which includes the following operations: supplying a crystalline semiconductor substrate, providing a porous region adjacent to a surface of the semiconductor substrate, introducing a dopant into the porous region from the surface, and thermally recrystallizing the porous region into a crystalline doping region of the semiconductor substrate whose doping type and/or doping concentration and/or doping distribution are/is different from those or that of the semiconductor substrate. A corresponding semiconductor structure is likewise provided.
摘要:
A method for producing a silicon substrate, including the steps of providing a silicon substrate having an essentially planar silicon surface, producing a porous silicon surface having a plurality of pores, in particular having macropores and/or mesopores and/or nanopores, applying a filling material that is to be inserted into the silicon, which has a diameter that is less than a diameter of the pores, inserting the filling material into the pores and removing the excess filling material form the silicon surface, if necessary, and tempering the silicon substrate that is furnished with the filling material that has been filled into the pores, at a temperature between ca. 1000° C. and ca. 1400° C., in order to close the generated pores again and to enclose the filling material.

摘要:
A sensor, in particular for the spatially resolved detection, includes a substrate, at least one micropatterned sensor element having an electric characteristic whose value varies as a function of the temperature, and at least one diaphragm above a cavity, the sensor element being disposed on the underside of the at least one diaphragm, and the sensor element being contacted via connecting lines, which extend within, on top of or underneath the diaphragm. In particular, a plurality of sensor elements may be formed as diode pixels within a monocrystalline layer formed by epitaxy. Suspension springs, which accommodate the individual sensor elements in elastic and insulating fashion, may be formed within the diaphragm.

摘要:
A capping technology is provided in which, despite the fact that structures which are surrounded by a silicon-germanium filling layer are exposed using ClF3 etching through micropores in the silicon cap, an etching attack on the silicon cap is prevented, namely, either by particularly selective (approximately 10,000:1 or higher) adjustment of the etching process itself, or by using the finding that the oxide of a germanium-rich layer, in contrast to oxidized porous silicon, is not stable but instead may be easily dissolved, to protect the silicon cap.
