Method for preparing large-size substrate |
摘要 |
A large-size substrate having improved flatness is prepared by measuring the flatness of one surface or opposite surfaces of a large-size substrate having a diagonal length of at least 500 mm, and partially removing raised portions on the one surface or opposite surfaces of the substrate by means of a processing tool on the basis of the measured data. The processing tool is adapted to blast a slurry of microparticulates in water carried on compressed air against the substrate.
