  • Patent number: 11733616
    Abstract: A photoresist supplying system includes a pump that includes a first tube phragm that stores a photoresist and a filter that filters the photoresist, a second tube phragm that stores the photoresist and is disposed outside the pump, where the second tube phragm transfers the photoresist to the first tube phragm, a storage unit that stores the photoresist, where the storage unit provides the photoresist to the second tube phragm, and a tube phragm drive unit that is connected to the first tube phragm. The tube phragm drive unit adjusts an interior volume of the first tube phragm and applies a pressure to a flexible outer wall of the first tube phragm to transfer the photoresist from the first tube phragm to a nozzle installed in the chamber. At least a part of the photoresist stored in the first tube phragm is transferred to the second tube phragm.

  • Patent number: 10996200
    Abstract: A method for determining a position of a fault of equipment includes receiving a plurality of sound source signals from a plurality of sound source inputting apparatuses, determining an abnormal operation of the equipment by analyzing at least one sound source signal among the sound source signals, and extracting abnormal sound source signals from the sound source signals. The abnormal sound source signals are indicative of abnormal operation of the equipment. The method further includes determining a position of the abnormal operation based on a time difference between the abnormal sound source signals.

  • Patent number: 10546765
    Abstract: A wafer perforating device includes a chuck stage configured to receive a wafer, a housing spaced apart in a vertical direction on the chuck stage, wherein at least one of the housing and the chuck stage moves in a first horizontal direction, and the housing and the chuck stage intersect each other on the first direction, a displacement sensor fixed within the housing and configured to measure a displacement with a surface of the wafer at a perforating point spaced apart periodically in the first direction of the wafer and a laser module fixed within the housing and configured to irradiate a laser into a perforating depth determined according to the displacement at the perforating point. The displacement sensor determines whether an upper particle and a lower particle are present at the perforating point by considering a step height of the displacement, and ignores the displacement of the perforating point with the presence of an upper particle.
