Abstract

A wafer transfer apparatus capable of simultaneously transferring multiple semiconductor wafers to and from a furnace or similar columnar wafer station. The apparatus has a cantilevered extension which extends from a main part. The extension is preferably mounted for pivotal movement. The extension has a distal engagement head mounted thereon. The distal engagement head is moved between a lateral position and an upstanding engaging position. The engagement head has a plurality of wafer support features which support the far edges of a group of wafers. The near edges of the wafers are held by proximal wafer contact heads.
