Abstract:
1. An exposure apparatus comprising: a projection system having a final element, the projection system projecting exposure light to an upper surface of a substrate through liquid between the final element and the upper surface of the substrate; an alignment system which detects a mark of the substrate; a liquid confinement member having a recovery outlet via which the liquid is removed along with gas, the recovery outlet being arranged such that the upper surface of the substrate faces the recovery outlet, the recovery outlet surrounding a path of the exposure light and the liquid confinement member confining the liquid to an area that is smaller than an area of the upper surface of the substrate by removing the liquid from a gap between the confinement member and the upper surface of the substrate via the recovery outlet; a first support member configured to support the projection system and the alignment system; a second support member configured to support the liquid confinement member; and an anti-vibration system disposed between the first support member and the second support member, the anti-vibration system is configured to limit vibration of (i) the first support member, (ii) the projection system supported by the first support member and (iii) the alignment system supported by the first support member.
