Abstract
A wafer carrier for processing a plurality of wafers includes a carrier body which rotatable about a central axis, and a plurality of pockets formed in the carrier body. Each of the pockets has an access opening and an inner periphery surface extending from the access opening to terminate at a floor surface. A lower periphery region of the inner periphery surface has a most distal region which is most distal from the central axis. When the carrier body is rotated about the central axis, a corresponding one of the wafers is less likely to be damaged due to a centrifugal force applied to the corresponding one of the wafers.
