At-Wavelength Metrology for EUV Lithography at NIST
Charles S. Tarrio, Steven E. Grantham, Robert E. Vest, Thomas B. Lucatorto
The National Institute of Standards and Technology (NIST) is active in many areas of metrology impacting extreme ultraviolet lithography. We will describe our activities in the areas of reflectometry, pulsed radiometry, and long-term multiplayer mirror endurance testing.
