Title: Fastener to connect flat part to profiled aluminum bar for use in clean rooms has base element of aluminum and plastic clamp element, so that flat part, base element, and bar present smooth surface
Inventor: BAIER WOLFRAM
IPC: E06B3/08
Filed: 1999-03-11
Abstract: The fastener (10) has a strip-like base element (11) locked to the bar (2) and a plastic strip-like clamp element (12).

Patent DE-19919471-A1 (DE)
Inventor: SPITZ RICHARD
IPC: H01L21/306
Filed: 1999-04-29
Abstract: The invention relates to a method for eliminating eruptions on, impurities in and/or damage to the crystal lattice of silicon bodies, in particular of superficially metallized and cut-out sections of a silicon wafer. According to said method, the silicon bodies are brought into contact, at least in certain areas, with a gas-type etching medium which selectively etches silicon by chemical reaction. During the etching process, gaseous reaction products are formed. An inter-halogen or fluorine pure gas compound which is in gaseous form or which has been converted into the gas phase is particularly suitable for use as the etching medium. The inventive method can be used, in particular, for producing power diodes which are cut out of a wafer or for overetching finished, mounted individual diodes.
