Abstract
A repair technique for shifter defects on phase shifting masks is described. It is based on the spin-coating of silicon-containing resist on the entire mask, electron beam exposure, and development. The new repair technique is quite simple because it does not require the deposition or removal of shifter materials. Both intrusion and extrusion shifter defects have been successfully repaired
