Abstract:
1. A lithography apparatus, comprising: a projection system configured to project a beam of radiation onto a substrate as an array of sub-beams of radiation; an array of individually controllable elements configured to modulate said sub-beams of radiation; and a data path including at least one data manipulation device arranged to at least partly convert data defining a requested pattern to a control signal suitable for controlling said array of individually controllable elements to form substantially said requested pattern on said substrate, wherein said at least one data manipulation device is arranged to carry out the conversion by applying a pseudo-inverted form of a point-spread function matrix to a column vector representing said requested pattern, said point-spread function matrix including information about the shape and relative position of the point-spread function of spots to be exposed on said substrate by one of said sub-beams of radiation at a given time.
