Abstract:
An immersion lithography apparatus having a controller configured to control a positioner to move a support table relative to an immersion space between the support table and a projection system to follow a route having a series of motions, the controller adapted to: predict a speed of an edge of the immersion space relative to an edge of an object on the support table when the edge of the immersion space passes over the edge of the object during at least one motion of the series of motions of the route; compare the speed to a predetermined parameter and to predict liquid loss from the immersion space during the at least one motion if the speed is greater than the predetermined parameter; and if liquid loss from the immersion space is predicted, modify one or more parameters of the route during the at least one motion accordingly.

Claim (Index 1):
An immersion lithography apparatus comprising:\n a support table configured to support an object; a projection system configured to project a patterned beam onto the object; a positioner configured to move the support table relative to the projection system; a liquid confinement structure configured to at least partly confine a liquid to an immersion space between the projection system and a surface of the object and/or the support table; and a controller configured to control the positioner to move the support table to follow a route comprised of a series of motions, the controller configured to at least:\n predict a relative speed between an edge of the immersion space and an edge of the object when the edge of the immersion space passes over the edge of the object occurring during at least one motion of the series of motions of the route; \n compare the speed to a predetermined parameter and predict liquid loss from the immersion space occurring during the at least one motion responsive to if the speed being greater than the predetermined parameter; and \n responsive to a prediction of liquid loss from the immersion space, modify one or more parameters of the route for the at least one motion accordingly.
