Zusammenfassung:	An edge exposure apparatus and method are disclosed. The edge exposure apparatus includes: a base frame (1); an edge exposure unit (2) mounted on the base frame and configured to perform an edge exposure process on a wafer; a pre-alignment unit (3) for centering and orienting the wafer and cooperating with the edge exposure unit (2) in the edge exposure process; a cassette unit (4) for storing and detecting the wafer; a robotic arm (5) for transferring the wafer; and a master control unit (6) for controlling the above components of the edge exposure apparatus. The edge exposure unit (2) and the pre-alignment unit (3) share a common worktable, resulting in structural compactness. Alternatively, two pre-alignment units (3) and two edge exposure units (2) may be included in order to increase processing efficiency.
