摘要

Specifications for advanced photomasks are becoming more and more stringent as the i8ndustry shifts to smaller lithography nodes. Among various requirements for photomasks, the need for stringent mean to target (MTT) control of critical dimensions (CDs) as well as the reduction of defects is the hottest issue for current photomask manufacturers.
