Claim 0:
1. A lithographic apparatus, comprising:
a patterning device support configured to support a patterning device, the patterning device comprising one or more two-dimensional (2D) features and configured to shape a radiation beam output from a source;
a projection system configured to:
suppress at least a zeroth order portion of the shaped radiation beam,
suppress interference between certain first order portions of the shaped radiation beam, and
direct at least an unsuppressed first order portion of the shaped radiation beam towards a substrate to form an image on the substrate according to the one or more 2D features,

wherein the projection system is configured to perform 2D interferometric printing by optical interference using the one or more two-dimensional (2D) features.
