Abstract:
A lithographic apparatus ( 10 ) and method for preventing exposure of a peripheral portion (P) of a substrate (S). An edge mask (M) has a radial concave edge (E) that extends over less than half a circle arch. The edge mask (M) is connected to a mask carrier ( 4 ) that circumnavigates the projection system ( 2 ) to adjust a tangential coordinate (Φ) and a radial coordinate (R) of the edge mask (M) with respect to the optical axis (A) of the projection system ( 2 ) for inserting the edge mask (M) at a variable distance into the beam of radiation (B). The tangential and radial positions (Φ,R) of the edge mask (M) are coordinated with a changing position (X,Y) of the substrate (S) to prevent exposure of the peripheral portion (P) of the substrate (S) during exposure of the target region (T).

Claim (Index 12):
The lithographic apparatus according to  claim 1 , wherein the controller is configured to control the tangential and radial mask drive mechanisms to move the mask carrier at the same time as the substrate drive mechanism is moving the substrate table.
