Claim 0:
1. A wafer processing method comprising:
mounting a wafer part on a chuck table;
loading the wafer part on the chuck table;
spraying, by a spray arm module, a first processing solution onto the wafer part to process the wafer part;
spraying, by the spray arm module, a second processing solution onto the wafer part to process the wafer part;
drying the wafer part on the chuck table; and
unloading the wafer part from the chuck table,
wherein the mounting of the wafer part on the chuck table includes:
holding the wafer part, by a transfer device including a lift, a transfer mechanism and a gripper, wherein the gripper includes a finger part which holds the wafer part through vacuum adsorption,
wherein the loading of the wafer part on the chuck table includes:
driving a chucking module including a base, a rotating part and a wafer restraining part of the chuck table and restraining, by the wafer restraining part, a retainer ring portion of the wafer part; and
moving, by a moving module including a moving rod and a cylinder or solenoid, a vacuum chuck unit of the chuck table and pulling the wafer part in a radial direction thereof to widen gaps between dies of the wafer part,
wherein the unloading of the wafer part from the chuck table includes:
returning, by the moving module, the vacuum chuck unit of the chuck table to an original position thereof to restore the wafer part to an original state thereof; and
driving the chucking module of the chuck table and releasing, by the wafer restraining part, the restraint of the retainer ring portion of the wafer part.
