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.

Transfer system for use with a horizontal furnace

A device for holding a semiconductor wafer cassette to enable manipulation of the cassette during semiconductor manufacturing processes is disclosed. The device includes a shielding plate for enclosing an open face of a semiconductor wafer cassette. A pair of gripping arms are pivotally connected to edges of the shielding plate for grasping the edges of a semiconductor wafer cassette in response to actuation by a trigger and linkage contained within a handle of the device. The trigger actuates the gripping plates between an opened and closed position. When the cassette is gripped, it may be manipulated in the horizontal and vertical directions by an operator using the handle of the device.
