Title: Wafer periphery exposure method and device therefor
Inventor: MIMURA YOSHIKI
IPC: H01L21/027
Filed: 2002-12-04
Abstract: PURPOSE: To provide a method and apparatus for exposing wafer periphery, which enables exposure without permitting an exposure region at a notch portion to cut into the inside of a wafer. CONSTITUTION: The wafer is mounted on wafer transfer pins 3 to have the peripheral location of the wafer detected by wafer periphery detecting sensors 4. Assuming that the wafer has a complete circular form, a control unit 20 obtains the center position of the wafer on the basis of the detected peripheral location data. Then the eccentricity between the center of wafer and the center of rotation of a rotary stage 1 is obtained. In accordance with the obtained data, the rotary stage 1 is moved, so that the center of wafer and the center of rotation of the rotary stage 1 coincide with each other. The wafer transfer pins 3 are then descended to mount the wafer on the rotary stage 1. In this state, the rotary stage 1 is rotated, followed by irradiating the wafer periphery with exposure beams of predetermined width for exposure of the wafer periphery. Since the wafer rotates in a state where there is no eccentricity, the wafer periphery can be exposed with a given width.
