ABSTRACT:
A mounting beam removal equipment has a cassette for holding a plurality of stacked wafers in such a manner that mounting beams of the wafers are trued up in the same direction, a brush composed of a plurality of disks which are inclined at a predetermined angle and secured to a vertical shaft along an axis of the vertical shaft at regular intervals, the brush facing a side of the mounting beams of the wafers held in said cassette. Furthermore, a rotation driving device is provided for rotating the brush about the axis of said vertical shaft, a first moving device is provided for moving the brush horizontally along the side of the mounting beams, and a second moving device is provided for moving the brush horizontally in a direction perpendicular to the side of the mounting beams. The second moving device moves the brush to the side of the mounting beams and brings the disks of the brush into contact with the side of the mounting beams, and the disks of the brush remove the mounting beams from said wafers while the rotation driving device rotates the brush and the first moving device moves the brush along the side of the mounting beams.
