Lithographic projection apparatus and device manufacturing method

摘要

A lithographic projection apparatus includes a radiation system for supplying a projection beam of radiation having a propagation direction, a support structure for supporting patterning structure, the patterning structure serving to pattern the projection beam according to a desired pattern, a substrate table for holding a substrate and a projection system for projecting the patterned beam onto a target portion of the substrate, wherein the lithographic projection apparatus further includes a sensor for measuring a movement of the projection beam perpendicular to its propagation direction and a controller to control a received dose of the projection beam on a target portion of the substrate in response to an output from the sensor.
