Aspects of the invention relate to techniques for repairing layout design defects after layout data have been processed by resolution enhancement techniques. The repair process first determines a re-correction region that includes three portions: core, transition and visible portions. An inverse lithography process is then performed on the core and transition portions of the re-correction region while taking into account effects from the visible portion to generate a modified re-correction region. The transition portion is processed based on distance from boundary between the transition portion and the core portion such that layout features near the boundary between the transition portion and the core portion are adjusted more than layout features farther away from the boundary.
