20090221112 | Method for Metallizing Semiconductor Elements and Use Thereof - The present invention relates to a method for metallizing semiconductor components in which aluminium is used. In particular in the case of products in which the process costs play a big part, such as e.g. solar cells based on silicon, a cost advantage can be achieved with the invention. In addition, the present invention relates to the use of the method, for example in the production of solar cells. | 09-03-2009 |
20100301456 | METHOD FOR APPLYING A STRUCTURE TO A SEMICONDUCTOR ELEMENT - A method for applying a predetermined structure of a structural material to a semiconductor element. The method includes the following steps: A) partially covering a surface of the semiconductor element with a masking layer, B) applying a film of a structural material to the masking layer and to the surface of the semiconductor element in the zones that are devoid of the masking layer and C) removing the masking layer together with the structural material present on the masking layer. The method according to the invention provides that between process steps B and C, the film of structural material is partially removed in a process step B2. | 12-02-2010 |

20100144079 | METHOD FOR THE PRECISION PROCESSING OF SUBSTRATES - The invention relates to a method for the precision processing of substrates, in particular for the microstructuring of thin layers, local dopant introduction and also local application of a metal nucleation layer in which a liquid-assisted laser, i.e. laser irradiation of a substrate which is covered in the regions to be processed by a suitable reactive liquid, is implemented. | 06-10-2010 |
20110233711 | METHOD FOR LOCAL CONTACTING AND LOCAL DOPING OF A SEMICONDUCTOR LAYER - 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. | 09-29-2011 |

20110108640 | SHOWER HEAD FOR A SANITARY SHOWER FITTING - A shower head for a hand-held shower attachment, an overhead shower attachment or a side shower attachment contains, in its shower-head housing, a vortex chamber which is of funnel shape with the side wall curved. The funnel begins, at the location of the largest diameter, in a radial plane and then decreases in diameter along a curved contour to an exit, where the walls of the funnel run in the axial direction. At the location of the largest diameter of the vortex chamber, upstream of this tapering region, the water is let in tangentially in the circumferential direction and in the axial direction. The vortex which is generated by virtue of the water being let in tangentially accelerates its speed of rotation in the direction of the spray disc. Arranged at the end of the tapering region is a jet-outlet chamber which is very flat, but is of large diameter in relation to the vortex chamber. The vortex travels into this jet-outlet chamber, and therefore, even in the outer region, water jets exit with a massage action out of the jet-outlet openings which are present there. | 05-12-2011 |

20080210509 | Method for Determining A Driving Torque Correction Factor for Compensating Cooperating Driving Torques of Different Drive Devices - A method and device for determining a driving torque correction factor for compensating the driving torques of a drive unit including a first drive device and a second drive device, both of which act with their driving torque on a common drive shaft. The method includes specifying and setting a desired driving torque for one of the two drive devices, adjusting a brake torque for the other of the two drive devices to a brake torque value, which is equivalent to the value of the actual driving torque (that occurs on the basis of the desired driving torque) of one of the two drive devices, and determining the correction value as a function of the specified desired driving torque of the one drive device and as a function of the brake torque value of the other drive device, the brake torque value being adjusted at the time of the compensation of the torques. | 09-04-2008 |

20130221115 | SANITARY FITTING - A sanitary fitting contains a rectilinear or slightly curved tubular outlet body, at one face end of which there is arranged an outlet, out of which the water flows, with the valve open, in a direction extending the direction of the outlet body. At this end of the outlet body there is arranged an actuating element for a valve cartridge arranged axially in the outlet body. At the opposite end of the outlet body there is arranged at a face end an actuating element for a valve cartridge accommodated in the outlet body. The outlet body has a lateral fastening attachment, by way of which the sanitary fitting is fastened to a horizontal or vertical surface and through which the supply lines are led. | 08-29-2013 |
