[0030] It can be seen that the present scheme can simultaneously cool the top surface and the bottom surface of the workpiece M by direct cooling of the cooling liquid, and the cooling efficiency is higher than the existing method of cooling the top surface of the workpiece M by the cooling liquid.
[0031] Moreover, the cooling liquid flowing out from the surrounding of the interlayer space 30 can also flush the debris on the workpiece table 1 to the surrounding to avoid too much debris remaining on the surface of the workpiece table 1.
