Exposure apparatus, exposure method and device manufacturing method
Abstract:
An exposure apparatus restricts reduction in throughput. The exposure apparatus controls movement such that, (1) when a substrate is moving in one direction, a first pattern is moved in a specified direction to expose a first shot region using a first exposure light, then movement of the substrate in the one direction continues while moving the second pattern in the specified direction to expose a second shot region, and (2) then the respective movement directions of the substrate and the second pattern are reversed to expose a third shot region using the second exposure light, then movement of the substrate in the reverse direction continues while moving the first pattern in a direction that is the reverse of the specified direction to expose a fourth shot region using the first exposure light.
