    摘要： The invention relates to an apparatus and to a method of forming thin films on substrate surfaces. It is the object of the invention to provide possibilities with which thin layers can be manufactured on substrate surfaces which have a specific layer material formation with desired properties. The apparatus in accordance with the invention is made such that a feed is present for at least one gaseous precursor, which contributes to the layer formation, at a reaction chamber region above a substrate surface to be coated. A source which is a plasma source and which emits electromagnetic radiation is moreover arranged such that a photolytic activation of atoms and/or molecules of the precursor(s) takes place with the emitted electromagnetic radiation. In this respect, the plasma source should be arranged and should also be operated such that no direct influence of the plasma on the substrate surface and on the precursors resulting in the layer formation takes place.

    摘要： The invention relates to a method for the selective plasmochemical dry-etching of phosphosilicate glass ((SiO2)xP2O5)y) formed on surfaces of silicon wafers. In this respect, it is the object of the invention to provide a cost-effective, efficient, selective possibility which at least reduces manufacturing losses and with which phosphosilicate glass can be removed from silicon wafers. A procedure is followed in the invention that crystalline silicon wafers, whose surface is provided with phosphosilicate glass, are etched in a selective plasmochemical process. In this connection, a plasma formed using a plasma source and an etching gas are directed at atmospheric pressure to the phosphosilicate glass which can thus be removed.

    摘要： A method and an apparatus relate to an ignition an arc between an anode and a cathode of a plasma source which can be used for a substrate surface modification at environmental atmosphere conditions. The cathode is arranged at a spacing from the anode. This method and the apparatus may reduce the effort for the ignition of an arc of a plasma source and to make the ignition process safer. The method is such that a barrier discharge is ignited with a supplied gas by means of two electrodes which are arranged parallel to the longitudinal axis between the anode and the cathode and are connected to a high-voltage generator and are supplied with a radio frequency electric AC voltage on the ignition. When an electric DC voltage is applied to the anode and to the cathode, an arc can thereby be ignited by means of the charge carriers present between the anode and the cathode due to the barrier discharge.

    摘要： A method for manufacturing photocatalytically active titanium dioxide layers on substrate surfaces. The method reduces the effort for the manufacture of photocatalytically active titanium dioxide layers and increases the choice for the coating of suitable substrate materials. In the method, a titanium compound present in the gas phase and water vapor are directed to a preheated substrate by means of gas phase hydrolysis and a titanium dioxide layer is foamed on the surface of the substrate by chemical reaction. In this respect, the titanium compound and water vapor are supplied separately from one another so that a flow speed of at least 0.5 m/s is achieved and the time between the first contact of the two gases up to the impact on the surface of the substrate is kept lower than 0.05 s, and in this process the photocatalytically active titanium dioxide layer is formed on the substrate surface.

    摘要： Solar cells are manufactured from P-type doped monocrystalline or polycrystalline silicon ingots by sawing wafers and applying an N-type doping. The wafers can be treated by etching them, in a plasma assisted process, with an etching gas containing or consisting of carbonyl fluoride. Hereby, the surface is roughened so that the degree of light reflection is reduced, or glass-like phosphorus-containing oxide coatings caused by phosphorus doping are removed. Carbonyl fluoride is also very suitable to selectively etch silicon oxide in silicon oxide/silicon composites.
