[Problems to be Solved by the Invention] However, in the single wafer handling method using a robot, when inserting the wafer into the groove of a mating carrier and when chucking the wafer in the groove with the chuck section of the robot, it is difficult to insert the wafer into the hard quartz groove. Grooves in the wafer or quartz are likely to chip and generate dust. Therefore, since a large force should not be applied suddenly to the wafer, it is necessary to carry out slow handling, which requires a long time. Furthermore, quartz carriers have poor precision and are easily deformed due to repeated heat treatments. For this reason, it is necessary to always measure the grooves of the quartz carrier on request, which poses problems in that measurement takes time and requires sophisticated and expensive technology.
