  • Publication number: 20230017834
    Abstract: A sub-fab area installation apparatus capable of reducing a power consumption used in manufacturing of semiconductors is disclosed. The sub-fab area installation apparatus includes: a vacuum pump configured to evacuate a processing gas from a processing chamber of the semiconductor manufacturing equipment; a cooling unit configured to cool a first circulation liquid used in the processing chamber; a heating unit configured to heat a second circulation liquid used in the processing chamber; an abatement device configured to detoxify the processing gas discharged from the vacuum pump; and a cooling-liquid line configured to pass a cooling liquid therethrough. The cooling liquid is supplied from a cooling source. The cooling-liquid line includes: a first downstream line, a second downstream line, and a third downstream line configured to supply the cooling liquid that has passed through the abatement device, the vacuum pump, and the cooling unit to the heating unit.

  • Patent number: 11527422
    Abstract: There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet.

  • Patent number: 5746790
    Abstract: A trap for collecting solid is connected to either an exhaust port or a suction port of a vacuum pump for trapping a solid material separated from a sublimed gas discharged by the vacuum pump. The trap includes a casing, a passage defining member disposed in the casing and defining a gas passage in the casing, and an intermediate member disposed between the casing and the passage defining member. The intermediate member is made of a flat thin sheet which is formed into a tubular member, and the tubular member is capable of being spread when taken out from the casing.
