Exposure apparatus, and device manufacturing method

Abstract

An exposure apparatus for projecting, by exposure, a pattern of an original onto a substrate. The apparatus includes a light blocking device for blocking at least a portion of exposure light. The light blocking device includes two plate-like members which are disposed in a vertical direction with a clearance kept therebetween, and two plate-like members which are disposed in a horizontal direction with a clearance kept therebetween. The apparatus further includes a driving member for moving the light blocking device, wherein the driving member includes the stator, and a reaction force absorbing device for absorbing a drive reaction force of the driving member. The reaction force absorbing device absorbs the reaction force by moving the stator of the driving member.
