Zusammenfassung:The present invention is directed towards a method for determining deformation parameters that a patterned device would undergo to minimize dimensional variations between a recorded pattern thereon and a reference pattern, the method including, inter alia, comparing spatial variation between features of the recorded pattern with respect to corresponding features of the reference pattern; and determining deformation forces to apply to the patterned device to attenuate the dimensional variations, with the forces having predetermined constraints, wherein a summation of a magnitude of the forces is substantially zero and a summation of moment of the forces is substantially zero.
