Abstract
A wafer transfer method which transfers a wafer with a disc shape to a groove for vertically placing the wafer therein, by use of a wafer holding hand, includes causing the wafer holding hand to hold the wafer at at least three support points on an edge of the wafer; moving the wafer holding hand holding the wafer to cause the wafer with a vertical posture in which the wafer is vertically oriented to be positioned above the groove for vertically placing the wafer therein; causing the wafer holding hand to cease to hold the wafer and to support the wafer at two support points on the wedge of the wafer; and moving the wafer holding hand supporting the wafer downward until the edge of the wafer moves into the groove for vertically placing the wafer therein.
