  • Publication number: 20100086947
    Abstract: Production of biopharmaceuticals from CHO cells requires generation of master-, working- and post-production cell banks of high quality, partly under GMP conditions. An optimal cryopreservation strategy is needed for each new production cell line, particularly with regard to the desire to establish production processes that are completely devoid of serum or even any animal components and to ensure robust thaw performance for reliable production. Here we describe a novel strategy employing flow cytometric (FC) analysis of Annexin V-stained cells for high-throughput characterization of CHO cell banks. Our data show that this method enables evaluation of a cryopreservation procedure just 6 h after thaw.

  • Patent number: 7354778
    Abstract: A method is provided for determining the end point during cleaning etching of processing chambers by means of plasma etching, which is used for carrying out coating or etching processes during the manufacture of semiconductor components. The invention provides a method for effectively and reliably determining the end point during cleaning etching of processing chambers. The end point is determined by monitoring the DC bias voltage on the plasma generator which is used for the plasma cleaning etching in the processing chamber in an evaluation unit. The plasma cleaning etching process is terminated by stopping the supply of the process gases in the gas supply unit and by switching off the plasma generator upon reaching a predetermined DC bias voltage value which corresponds to completion of the cleaning etching process.

  • Publication number: 20060057689
    Abstract: Processes for preparing fatty acids are described wherein a C4-C12 fatty acid methyl ester is subjected to hydrolysis in the presence of an enzyme to form an organic phase comprising a C4-C12 fatty acid and an aqueous phase comprising methanol, wherein at least a portion of the methanol is continuously removed; and the organic phase is subsequently separated from the aqueous phase, and optionally, where the organic phase further comprises an unhydrolyzed portion of the C4-C12 fatty acid methyl ester, the unhydrolyzed portion of the C4-C12 fatty acid methyl ester is separated from the C4-C12 fatty acid.

  • Patent number: 6979522
    Abstract: A batch of semiconductor wafers are exposed after an alignment in a wafer stepper or scanner and each of their alignment parameters are determined. Using, e.g., a linear formula with tool specific coefficients, the overlay accuracy can be calculated from these alignment parameters in advance with a high degree of accuracy as if a measurement with an overlay inspection tool had been performed. The exposure tool-offset can be adjusted on a wafer-to-wafer basis to correct for the derived overlay inaccuracy. Moreover, the alignment parameters for a specific wafer can be used to change the tool-offset for the same wafer prior to exposure. The required inspection tool capacity is advantageously reduced, the wafer rework decreases, and time is saved to perform the exposure step.
