Abstract:
A substrate holding apparatus which can prevent a liquid from entering into a rear surface side of a substrate. A substrate holding apparatus is provided with a base material, a first holding portion formed on the base material to hold the substrate, and a second holding portion formed on the base material to hold a plate member by surrounding the circumference of a processing substrate held by the first holding portion. The second holding portion holds the plate member so as to form a second space on the side of the rear surface of the plate member. On the rear surface of the plate member, an absorbing member is arranged to absorb the liquid entered from a gap between the substrate held by the first holding portion and the plate member held by the second holding portion.

Claim (Index 1):
An exposure apparatus that exposes a substrate via liquid, the exposure apparatus comprising:\n a projection optical system to project an image of an object; a stage to move the substrate with respect to a projection area where the image of the object is projected by the projection optical system; and a liquid immersion mechanism to supply liquid onto a part of the stage to locally form a liquid immersion region such that the liquid immersion region includes the projection area, wherein the liquid immersion mechanism comprises a nozzle member having a supply port from which liquid is supplied onto the stage, the supply port being provided on a lower surface of the nozzle member, the lower surface of the nozzle member being arranged so as to face the stage, wherein the stage comprises a substrate holder to hold the substrate, the substrate holder including a plurality of supporting portions to support the substrate, a first circumferential wall provided surrounding the supporting portions, and a second circumferential wall provided surrounding the first circumferential wall, and wherein the first circumferential wall and the second circumferential wall are arranged so as to face the substrate while the substrate is supported by the supporting portions.
