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 7):
The lithographic apparatus according to  claim 1 , wherein the mask carrier is moveably connected to a stationary frame.
