摘要:
PROBLEM TO BE SOLVED: To provide a double-side grinding apparatus capable of uniformly grinding a wafer and also reducing occurrence of flaws on an outer peripheral part of the wafer to the minimum extent possible. SOLUTION: A coating layer 51 with a predetermined width and a required thickness is formed of a wear-resistant material along a periphery of a through hole 49 on upper and lower surfaces of a carrier body 44a. In addition, a shock-absorbing ring 53 made of resin with the same thickness as that of the carrier body 44a and with a required width is attached to an inner peripheral wall of the through hole 49. The wafer 55 is held in the shock-absorbing ring 53. COPYRIGHT: (C)2011,JPO&INPIT
