  • Publication number: 20220319853
    Abstract: Disclosed is a substrate processing method including: a pressurizing operation of raising a process pressure from a first pressure (P1) to a second pressure (P2) that is greater than the atmospheric pressure; a depressurizing operation of lowering the process pressure from a sixth pressure (P6), which is greater than the atmospheric pressure, to a seventh pressure (P7); and an annealing operation of changing the process pressure into a preset pressure change pattern between the pressurizing operation and the depressurizing operation, under a temperature atmosphere of a second temperature (T2) higher than the room temperature. A temperature raising operation of raising a temperature atmosphere from a first temperature (T1) to the second temperature (T2) is performed from a preset temperature raising start point (t1) to a preset temperature raising end point (t2) while the pressurizing operation is performed or after the pressurizing operation is performed.

  • Patent number: 11323560
    Abstract: An illegal call detection apparatus comprises a data collecting unit, a preprocessing unit, and a learning unit. The data collecting unit collects, from at least one of a subscriber terminal or a call exchanger, a raw packet generated by the subscriber terminal using a VoIP service, and collects, from the billing server, CDR data related to the raw packet. The preprocessing unit generates learning data by using service usage information extracted from the CDR data and service detailed information extracted from the raw packet, and generates a training image by converting the training data into an image according to a predetermined imaging rule. The learning unit extracts at least one or more features from the training image, and learns whether the training image is related to an illegal call by using the features, through an illegal call detection model.
