A mathematical model of the Nikon Lampas Reflection Measuring Microscope for the fine-line lithography in integrated circuit manufacture has been developed. Optical intensity profiles of a perfect line were computed using computer software supplied by the National Bureau of Standards. The programs were modified for the Lampas microscope. From line profiles, the accuracy of the microscope was calculated. The microscope is accurate down to 6/10 of a micron. All lines below 6/10 of a micron were unresolved.
