Abstract: PURPOSE:To position a wafer at the time of removing the wafer from a cassette or containing it therein and to reduce adherence of dusts to the wafer by allowing a wafer pressing member to protrude on the upper surface of the opposite end of a suction hand to a cassette entrance side, and supporting the wafer at three points of a vacuum suction unit and two protrusions at the time of conveying the wafer. CONSTITUTION:When a wafer is removed from a cassette and conveyed, a suction hand 11 is advanced to a cassette 21, pins 12, 12 are brought into contact with a wafer 23, and the wafer 23 is pressed to the back surface side of the cassette 21. Then, a vacuum generator is operated, the cassette 21 is moved down, the wafer 23 is carried by the upper surface of the hand 11, and sucked. With this structure, even if the wafer 23 containing position in the cassette 21 is irregular, it can be always corrected substantially to a predetermined position. Since the wafer on the hand 11 is supported at three points of the protruding wall 13b of a vacuum suction unit 13 and two protrusions 14, 14, the contact area of the rear surface of the wafer 23 with the hand 11 is largely reduced as compared with prior art, and adherence of dusts to the rear surface of the wafer 23 is remarkably reduced.
