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.

摘要： An exposure apparatus is provided with a projection optical system, and the projection optical system includes a first optical element disposed most closely to an image plane of the projection optical system. The exposure apparatus includes a first liquid immersion mechanism which forms a first liquid immersion area of a first liquid between the first optical element and an upper surface of a transparent member provided on a side of the image plane of the projection optical system, and an observation unit which observes a state of the first liquid immersion area. It is possible to grasp the state of the liquid immersion area of the liquid, thereby executing optimum liquid immersion exposure.
