Patent ID: 7482611

Claim:
A lithographic apparatus, comprising: a measurement station including a measurement system configured to measure (i) a location of each of a plurality of points on a substrate and (ii) a height, a tilt, or both of each of a plurality of points on the substrate, the measurement system, in use, not measuring through liquid adjacent the substrate; an exposure station including a projection system configured to expose a patterned beam onto a substrate; a liquid supply system configured to provide a liquid to a substrate so that during exposure, there is liquid in a space between the projection system and a substrate; a first substrate table configured to hold a first substrate in the measurement station so as to be measured and is movable from the measurement station to the exposure station; a second substrate table configured to hold a second substrate in the exposure station so as to be exposed to the patterned beam passing through the liquid; and a positioning system configured to move the first substrate table so that measurement of the first substrate at the measurement station can be performed at least partially overlapping in time with exposure of the second substrate at the exposure station and configured to move the second substrate table during exposure using the location and the height, the tilt, or both data measured when the second substrate table was at the measurement station.
