Table of wafer polishing apparatus, method for polishing semiconductor wafer, and method for manufacturing semiconductor wafer

摘要

A table for a wafer polishing apparatus having superior heat-resistant, anti-thermal-shock, and anti-abrasion characteristics and capable of increasing the diameter of a semiconductor wafer while improving the quality of the wafer. The table includes a plurality of superimposed bases each of which is formed of silicide ceramic or carbide ceramic. The bases are joined together by an adhesive layer. A fluid passage is formed in a joining interface between the bases.
