Claim Text:
1. An exposure apparatus that exposes a plurality of exposure shots on a substrate, the apparatus comprising: a stage configured to hold the substrate; a driving unit configured to drive the stage; a processor configured to create a target locus of the stage; and a control unit configured to control the driving unit based on the created target locus created by the processor, wherein the processor creates the target locus using constrained-quadratic-linear programming for deriving a driving time of the stage so that the driving time from an end of an exposure of a first exposure shot to a start of a next exposure of a second exposure shot as a target function falls within an acceptable range, and wherein the constrained-quadratic-linear programming is executed under constrained conditions of an arrangement of the exposure shots, an exposure order of the exposure shots, an upper limit of a velocity of the stage, an upper limit of an acceleration of the stage, and a lower limit of a time required for jerk of the stage.
