    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.

    摘要： The invention provides aqueous flux preparations with increased dynamic viscosity. In the flux preparations, irreversibly dehydrated K 2 AlF 5 (also denoted as orthorhombic K 2 AlF 5 or phase II salt) provides for an increase of the dynamic viscosity if the aqueous flux preparations are aged, i.e. a contact between water comprised in the preparation and irreversibly dehydrated K 2 AlF 5 is maintained for a certain time span, preferably for at least 12 minutes. The higher viscosity improves the brazing process, for example because less flux preparation drops off from the parts to be brazed.

    摘要： The invention provides a container containing a fluorinated organic carbonate and a gas atmosphere which contains cover gas selected from the group consisting of a noble gas, e.g., argon, xenon, a gaseous fluorinated aliphatic carbon which is heavier than air and does not interfere with the fluorinated organic compound, and SF 6 , or any mixture thereof,. Fluorinated organic carbonates are highly suitable as solvents or additives for solvent in Li ion batteries and consequently, must be kept in a very pure state even during expanded times of storage. The argon or xenon gas atmosphere prevents the intrusion of air or moisture even if the container is opened and the liquid handled in an environment of common air. The invention also provides for a method of storing fluorinated organic carbonates in a safe manner.

    摘要： Process for the removal or recovery of fluorine from fluorine containing waste gases Waste gases, especially those from pro cesses used in the semiconductor industry, e.g. from etching silicon wafers or clean ing processing chambers with elemental fluorine, are contacted with a metal or metal compound which reacts with the fluorine contained in the waste gas mi xtures forming a metal fluoride which comprises reversibly bound fluorine. Pref erably, a manganese fluoride is applied which forms manganese tetrafluoride which, in turn, can be heated to split off elemental fluorine. The process allows the recovery of elem ental fluorine in a pure form suitable for reuse. No figure
