摘要:
A micromechanical structure and a corresponding manufacturing method. The structure includes a substrate, which includes an anchoring device, and a centrifugal mass, which is connected to the anchoring device via a flexible spring device, so that the centrifugal mass is elastically deflectable from its rest position. The centrifugal mass includes clearances and is configured to be deflectable by etching a sacrificial layer underneath it. The sacrificial layer is present in a first area located underneath the centrifugal mass with a first etchable thickness, and in a second area located underneath the centrifugal mass with a second etchable thickness, the second thickness is greater than the first thickness. The centrifugal mass is structured in the first area so that in etching only a maximum of two etching fronts may come together in order to limit the etching residue deposits.

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.

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.

A method for fabricating a pair of large surface area planar electrodes. The method includes forming a first template above a first substrate, the first template having a first plurality of pores, coating the first plurality of pores of the first template with a first layer of conducting material to form a first electrode, placing the first plurality of pores of the first electrode in proximity to a second electrode, thereby forming a gap between the first plurality of pores and the second electrode, and filling the gap with an electrolyte material.
摘要:
A production method for chips, in which as many method steps as possible are carried out in the wafer composite, that is, in parallel for a plurality of chips disposed on a wafer. This is a method for producing a plurality of chips whose functionality is implemented on the basis of the surface layer of a substrate. In this method, the surface layer is patterned and at least one cavity is produced below the surface layer, so that the individual chip regions are connected to each other and/or to the rest of the substrate by suspension webs only, and/or so that the individual chip regions are connected to the substrate layer below the cavity via supporting elements in the region of the cavity. The suspension webs and/or supporting elements are cut when the chips are separated. The patterned and undercut surface layer of the substrate is embedded in a plastic mass before the chips are separated.

摘要:
A method for manufacturing chips (1, 2), in which at least one diaphragm (11, 12) is produced in the surface layer of a semiconductor substrate (10) spanning a cavity (13). The functionality of the chip (1, 2) is then integrated into the diaphragm (11, 12). In order to separate the chip (1, 2), the diaphragm (11, 12) is detached from the substrate composite. The method according to the present invention is characterized by metal plating of the back of the chip (1, 2) in an electroplating process before the chip is separated.

摘要:
A process for manufacturing a component is described. In a first manufacturing step a base structure having a substrate, a diaphragm, and a cavern region is provided. The diaphragm is oriented substantially parallel to a main plane of extension of the substrate. The cavern region is situated between the substrate and the diaphragm, and has an access opening. In a second manufacturing step, a first conductive layer is provided at least partially in the cavern region, in particular on a second side of the diaphragm facing the substrate, perpendicularly to the main plane of extension.
