  • Patent number: 11972946
    Abstract: The present inventive concept relates to a method for removing impurities in thin film and a substrate processing apparatus. The method for removing impurities in a thin film includes the steps of: providing a substrate having a thin film formed thereon in a process chamber; supplying a first gas reacting and coupling with impurities contained in the thin film, into the process chamber; exhausting a coupled product of the impurities and the first gas by depressurizing an interior of the process chamber after stopping the supply of the first gas; curing the thin film by supplying a second gas being different from the first gas into the process chamber; and stopping the supply of the second gas and exhausting the remaining second gas from the interior of the process chamber.

  • Patent number: 11020037
    Abstract: An R wave peak detection method uses the periodicity of an electrocardiogram signal, in which expected R wave peaks are detected from an electrocardiogram signal, and a time difference between the expected R wave peaks that are detected is calculated in order to output, as actual R wave peaks, only expected R wave peaks that are greater than a threshold time difference, thereby avoiding a case in which the R wave peaks are erroneously detected from an non-ideal electrocardiogram signal.
