Abstract:
A liquid immersion exposure apparatus includes a liquid immersion member which forms a liquid immersion space on an object disposed opposite to an emitting surface of an optical member. The liquid immersion member includes (i) a first member that has a first liquid supply port, and a first opening, through which exposure light is projected and (ii) a second member that has a first liquid recovery port facing downwardly and a second liquid supply port and that is movable with respect to the first member. The first member has a second liquid recovery port. The first liquid supply port faces an outer surface of the optical member and is provided on one side of the optical member. The second liquid recovery port faces the outer surface of the optical member and is provided on the other side of the optical member.

Claim (Index 1):
A liquid immersion exposure apparatus comprising:\n a projection system having an optical member via which exposure light is projected; and a liquid immersion member which is used for forming a liquid immersion space on a surface of an object opposite to an emitting surface of the optical member, wherein: the liquid immersion member includes (i) a first member that has a first liquid supply port, and a first opening, through which the exposure light is projected and (ii) a second member that has a first liquid recovery port facing downwardly and a second liquid supply port and that is movable with respect to the first member, the first member has a second liquid recovery port, the first liquid supply port faces an outer surface of the optical member and is provided on one side of the optical member, the second liquid recovery port faces the outer surface of the optical member and is provided on the other side of the optical member, and the second member is moved in a direction perpendicular to an optical axis of the optical member so that a relative speed between the second member and the object is smaller than a relative speed between the first member and the object, while recovering liquid in a gap between the second member and the object via the first liquid recovery port of the second member.
