Abstract: Method of selectively etching a first material on a substrate with a high selectivity towards a second material by flowing a liquid etchant across a substrate surface at a flow sufficiently fast to generate a minimum mean velocity parallel to the substrate's surface, wherein the first material is selected from a group including materials with semiconducting properties based on at least two different chemical elements.

Abstract: A reflex algorithm for assessing cardiac patients, which does not require human decision-making in selecting assays to be performed. Performance of further biochemical marker tests on a patient is dependent upon the outcome of previously conducted tests. The reflex algorithm focuses on obtaining the most accurate test information as early as possible from several different tests run in very short intervals. The reflex algorithm may be implemented by a computer that can copy requests for the most appropriate test to the loadlists of automated clinical chemistry and immunoassay analyzers. Also provided is an integrated platform for executing clinical chemistry assays and immunoassays according to a reflex algorithm.

Abstract: A process of controlled wet etching of semiconductor wafers having a silicon dioxide layer on each of two surfaces, includes entirely removing the silicon dioxide layer from a top side and selectively removing the silicon dioxide layer from the opposite side bottom in a defined area which extends to the inside from the peripheral edge of the semiconductor wafer using an etching medium which includes hydrofluoric acid or a combination of hydrofluoric acid and ammonium fluoride and at least one carboxylic acid.

Abstract: In order to remove, after treatment of wafer-shaped articles (2), prefera a silicon wafer, with a treatment medium, preferably with an etching fluid, on the bottom of wafer-shaped article (2), i.e. the side facing chuck (1) for wafer-shaped article (2), residual treatment medium adhering in its edge area, there is nozzle (20) from which flushing liquid, preferably deionized water, can be sprayed onto the outside edge of article (2) and between chuck (1) and wafer-shaped article (2). The flushing liquid, which penetrates more or less deeply, depending on the pressure with which the flushing liquid emerges from nozzle (20) and depending on the alignment of nozzle (20) relative to wafer-shaped article (2), is flung off again by the rotation of wafer-shaped article (2) and in doing so entrains residues of treatment medium. For optimum action the alignment of nozzle (20) can be changed relative to edge (16) of wafer-shaped article (2).

Abstract: An apparatus which controls the operation of metering pumps serving to regenerate the baths in a developing machine for exposed photosensitive material issuing from a photocomposing machine has a computer whose outputs transmit appropriate signals to the metering pumps via amplifiers and whose inputs respectively receive signals from a scanner serving to ascertain the width of photosensitive material in the photocomposing machine and the composition of the emulsion, from a forward-reverse counter which ascertains the total length of photosensitive material admitted into the developing machine per unit of time, and from an integrating circuit which receives signals denoting the amounts of radiation issuing from a cathode ray tube or a laser recorder and impinging upon the photosensitive material. This renders it unnecessary to monitor the condition of the baths and/or the photosensitive material in the developing machine.
