WAFER FLIP APPARATUS

摘要

WAFER FLIP APPARATUS Apparatus is disclosed for automatically transferring a semiconductor wafer between a horizontal and a vertical plane, beginning and ending in precisely located positions. A wafer support arm is carried by a transfer member which also includes means for rotating the support arm between a "start" position and an intermediate position in a horizontal plane. Means are provided for rotating the transfer member to position the support arm in a vertical plane. The wafer support arm is then returned to its original position relative to the transfer means, thus establishing a "finish" position in the vertical plane.
