  • Patent number: 6071350
    Abstract: An apparatus for manufacturing a semiconductor device employs a vacuum system, in which a heating source is installed in a predetermined portion of a venting-gas inlet. A venting-speed controlling valve is installed in a predetermined portion of an exhaust pipe, for controlling the speed of gas flowing from a load lock chamber to a pump by controlling the opening and closing thereof. An exhaust pipe may have a main pipe with different diameters in different portions to reduce the venting speed. Accordingly, condensation-induced particle formation can be reduced by thus preventing adiabatic expansion of the gas in a load lock chamber.
