    Patent number: 5839870
    Abstract: An apparatus for preventing the cross contamination of heating element within horizontal furnaces is disclosed. A rotating spindle may connect to either or both of the lifting arm of a triaxial loader or the transfer plate of a loading station. A pair of spindles are able to lift a single wafer boat. Each spindle includes a plurality of active positions with one active position associated with each heating element of the horizontal furnace. A control processor monitors the position of the spindle and rotates the spindle to the active position associated with a heating element when a loading or unloading process is initiated for that heating element.
