  • Patent number: 9587267
    Abstract: The invention relates to a method for the quantification of one or more nucleic acids in a sample, for example: making a sample available which contains at least one nucleic acid to be quantified, adding an oligonucleotide probe, the oligonucleotide probe comprising a sequence which can specifically hybridize to the nucleic acid to be quantified or to a common sequence of the nucleic acids to be quantified, incubating the sample under conditions which allow the hybridization of the oligonucleotide probe to the nucleic acid(s) to be quantified, incubating the sample under conditions which allow the extension of hybridized probes, the nucleic acid(s) serving as a template in each case, removing the non-hybridized probes from the sample and quantifying the hybridized oligonucleotide probes to measure the quantity of the nucleic acid(s) to be quantified. The invention also relates to a kit for carrying out said method.

  • Patent number: 9490141
    Abstract: A method for planarizing a semiconductor device includes steps herein. A substrate is provided, on which a stop layer is formed. A trench is formed in the substrate. A first semiconductor film is deposited conformally on the stop layer and the trench. A second semiconductor film is deposited to fill the trench and cover the first semiconductor film. A chemical-mechanical polishing process is performed until the stop layer is exposed. A removal rate of the chemical-mechanical polishing process on the first semiconductor film is higher than that on the second semiconductor film. The first dielectric layer on the substrate selectively is removed.

  • Publication number: 20160298182
    Abstract: The present invention relates to methods and uses for the detection or quantification of newly-synthesized double-stranded target nucleic acid molecules in a sample during quantitative real-time polymerase chain reaction (qPCR) amplification. According to the invention, an intercalating dye recognizing double-stranded DNA molecules with higher affinity than single-stranded DNA molecules and a fluorophore-labeled oligonucleotide-probe being sequence specific for a target nucleic acid molecule are simultaneously employed, thus enabling quantification a specific target and total amount of a mixed nucleic acid population, and enabling assessing the cause of suboptimal PCR performance.
