| 摘要 |
A system for inspecting an extreme ultra violet (EUV) mask. The system includes an array of sensors and an optical system. The array of sensors is configured to produce analog data corresponding to received optical energy. The optical system is configured to direct EUV light from an inspection area of an EUV patterning device onto the array of sensors, whereby the analog data is used to determine defects or to compensate for irregularities found on the EUV mask.
