Abstract: Fluorine is deposited on a semiconductor substrate surface according to a novel process. A semiconductor substrate is placed in a reaction chamber and the substrate surface is wetted with water and/or alcohol. A compound containing fluorine is led to the substrate surface, so that a cleaned semiconductor surface covered with fluorine is produced, and the compound containing fluorine is removed from the reaction chamber. The cleaned semiconductor surface covered with fluorine is then wetted with a mixture containing at least 10% by volume of water and at least 10% by volume of alcohol, for producing a cleaned semiconductor surface covered with a predetermined amount of fluorine. The predetermined amount of fluorine is lower the higher a proportion of water in the mixture is chosen to be. Then, the water and the alcohol are removed from the semiconductor surface.

Abstract: In a method for producing a titanium monophosphide layer, a carrier is first placed in a reactor. Thereafter, a TiN layer is deposited on the carrier by supplying TiCl4 ad NH3 into the reactor. The TiN layer is annealed immediately after deposition of the TiN layer while PH3 is supplied to the reactor, in order to form the titanium monophosphide layer on the TiN layer.

Abstract: A method for rapid thermal processing (RTP) of a silicon substrate, the substrate having a surface with a plurality of areas implanted with dopant ions, comprising a) contacting the surface with a reactive gas, b) processing the substrate for a first process time and temperature sufficient to produce a significant protective layer upon the surface, and c) annealing the substrate for a second process time and temperature sufficient to activate the dopant material so that the sheet resistivity of the implanted areas is less than 500 ohms/square, where the first and second processing time and temperature are insufficient to move the implanted dopant ions to a depth of more than 80 nanometers from the surface.
