  • Patent number: 11521867
    Abstract: A cutting apparatus includes a cassette table on which a first cassette in which a frame unit, ring-shaped frame and wafer are housed, and a second cassette in which a simple wafer is housed. A first conveying unit having a first frame holding part holds the ring-shaped frame of the frame unit withdrawn from the first cassette and conveys the frame unit to a chuck table. A first wafer holding part holds the simple wafer withdrawn from the second cassette and conveys the simple wafer to the chuck table. A cutting unit cuts the wafer, and a second conveying unit conveys the frame unit from the chuck table to a cleaning unit. A second wafer holding part holds the cut simple wafer and conveys it from the chuck table to the cleaning unit.

  • Publication number: 20210043473
    Abstract: An edge trimming apparatus includes a chuck table that causes a ring-shaped groove with an outer diameter smaller than the outer diameter of a wafer to communicate with a suction source to hold under suction a lower surface of the wafer by the ring-shaped groove, a cutting unit that rotates a cutting blade and annularly cuts a circumferential part of the wafer held by the chuck table, and a cleaning unit that cleans a region outside the ring-shaped groove in the upper surface of the table and the upper surface of the table including the ring-shaped groove. The cleaning unit is positioned to the region outside the ring-shaped groove in the upper surface of the table and the upper surface of the chuck table including the ring-shaped groove, and the chuck table is rotated to clean the ring-shaped groove and the upper surface.

  • Patent number: 9463542
    Abstract: A holding table for holding a platelike workpiece which includes a base and an annular holding member attached to the base. The annular holding member has an annular holding surface for holding the outer circumferential portion of the platelike workpiece thereon. Accordingly, a central recess is defined by the base and the annular holding member so as to be surrounded by the annular holding member. The annular holding member is formed with a suction opening exposed to the annular holding surface, a vacuum line having one end communicating with the suction opening and the other end connected to a vacuum source, a discharge opening exposed to the annular holding surface at a position radially outside of the suction opening, and a fluid line having one end communicating with the discharge opening and the other end connected to a fluid source.
