GAITHERSBURG, Md., March 12 -- New measurements of key wavelengths of ultraviolet light -- down to a few millionths of a nanometer -- are among the most precise ever reported and are improving calibrations of microlithography tools used in making integrated circuits, such as those in computer chips. The dimensions involved are 10,000 times smaller than hydrogen atoms, the smallest of all atoms. To make the measurements, physicists at the National Institute of Standards and Technology (NIST) used a spectrometer so sophisticated that it is one of only five of its kind in the world, two of which...Read full articleRelated content from Photonics MediaArticlesUV-based 3D Printing Accelerates Multipurpose Glass ProductionCurrent 3D-printing techniques for fabricating glass involve time-consuming processes that require high temperatures and considerable resources to complete.
