Abstract
Photomask is a key factor to support the lithography technology. Defect repairing technology has become more important than ever to keeping the photomasks' integrity in the manufacturing processes. The SIR5000 is a photomask defect repair system for ArF/90 nm generation lithography. In this work, the repaired masks by the SIR5000 were evaluated by an Aerial Imaging Microscope System (AIMS) and Atomic Force Microscope (AFM). These test results do not show actual printing condition on wafer, but rather a simulated lithography image. In this paper, we present the imaging damage, the edge placement repeatability, the repair area's transmission and the printing performance on wafer. An ArF scanner was employed for the tests on the imaging damage and the printing performance. The transmission of imaged area is more than 95% after 70 scanning frames. The edge placement has shown the 90 nm node repair capability. The transmission of repaired area is no issue by AIMS193 analysis. The actual printing result on wafer has shown there is no printing issue. The SIR5000 is well suited for ArF generation lithography.
