Abstract:
In a carrier system, a chuck unit is used to hold a placed wafer from above, and vertical-motion pins use suction to hold the wafer from below. Then, the chuck unit and the vertical-motion pins are subsequently lowered until a bottom surface of the wafer comes into contact with a wafer table. During the lowering, the holding force exerted by the chuck unit and the arrangement of chuck members are optimally adjusted such that, as a result of the restraint of the wafer by the chuck unit and the vertical-motion pins, localized surplus-restraint is imparted to the wafer, and warping does not occur.

Claim (Index 16):
A carrier system that carries in a plate-like object to a holding member provided with an object mounting surface on an upper surface, the system comprising:\n a suction unit having a base member and a plurality of suction members that are provided at the base member and each generate a suction force to suction the object by generating a flow of gas around the object, the suction unit being capable of suctioning a surface of the object, from above in a noncontact manner, that is carried to above the holding member located at a predetermined carry-in position, and the suction unit being vertically movable; a gas supply device that supplies gas to the plurality of suction members; a support section that is provided at the holding member, is capable of changing a relative position with respect to the object mounting surface in a vertical direction, and is capable of supporting a part of a center section area of an other surface of the object from below, the other surface being on a side opposite to the surface of the object; a drive device that is capable of changing a relative position between the suction unit and the support section, and the object mounting surface in at least the vertical direction; and a controller that controls the gas supply device and the drive device, wherein the controller:\n supports from below the part of the center section area of the other surface of the object suctioned by the suction unit, using the support section; and \n controls the gas supply device to weaken the suction force by the suction member with respect to a first area of the surface of the object, compared to the suction force with respect to a second area of the surface of the object, the first area corresponding to the center section area that includes a supporting point by the support section, and the second area being on an outer circumference side of the first area, and \n the controller controls the drive device to move downward the suction unit and the support section toward the object mounting surface in a state of maintaining a suctioning state of the object by the suction unit and a supporting state of the object by the support section.
