Abstract:
A difficulty of contamination interfering with a grid plate positional measurement system is addressed. In one embodiment contamination is prevented from coming into contact with the grating or the sensor. In an embodiment, surface acoustic waves are used to detach contamination from a surface of the grating or sensor.

Claim (Index 20):
A device manufacturing method comprising projecting a patterned beam of radiation onto a substrate held on a substrate table, wherein a position of the substrate table relative to the projection system is measured using a grating and a sensor, wherein a barrier is positioned to hinder contamination from reaching the grating or sensor, the barrier having a surface facing away from the associated grating or sensor at a distance between 300 \u03bcm and 5 mm from the associated grating or sensor.
