发明名称 Exposure apparatus, exposure method and device manufacturing method
摘要 An exposure method sequentially exposes a plurality of shot areas of a substrate. The method includes: (i) holding the substrate on a substrate holder such that a gap is formed along an edge of the substrate; (ii) exposing one of the shot areas, located near a center of the substrate, through a liquid of a liquid immersion area which covers only a portion of a surface of the substrate, while moving the substrate at a first scanning speed; and (iii) exposing an other one of the shot areas through the liquid of the liquid immersion area, while moving the substrate at a second scanning speed lower than the first scanning speed. The other one of the shot areas is located near the edge of the substrate and the gap is included in the liquid immersion area during the exposure of the other one of the shot areas.
