Abstract
The present invention relates to a sheet for mounting a workpiece and a method for making the same. The method includes the steps of: (a) providing a sheet body having a top surface, a bottom surface, at least one side surface and a plurality of pores, wherein some of the pores open at the side surface; and (b) sealing or narrowing the pores that open at the side surface. Since the pores that open at the side surface are sealed or narrowed, the slurry is prevented from entering into the interior of the sheet body. Therefore, the infiltration distance reaches a predetermined value slowly, thereby increasing the effective life of the sheet.
