Abstract
The inspection of alternating phase shifting masks is still one of the major challenges in state-of-the-art mask making. Main issue is that phase defects cannot easily be identified by inspection systems using an inspection wavelength different form the target exposure wavelength. The paper presents inspection results using the Aera193, an aerial image based mask inspection system.
