摘要: An optical sensor apparatus for use in an extreme ultraviolet lithographic system is disclosed. The apparatus includes an optical sensor comprising a sensor surface and a removal mechanism configured to remove debris from the sensor surface. Accordingly, dose and/or contamination measurements may be carried out conveniently for the lithographic system.
