N&k Technology

n&k technology, inc., of san jose, california, was founded in 1992 by drs. rahim forouhi and iris bloomer. n&k technology manufactures state-of-the-art optical metrology tools for the semiconductor, photomask, data storage, flat panel display and solar cell industries. the company offers exceptionally high resolution thin film and scatterometry measurement systems. n&k's thin film measurement systems accurately and repeatably determine thicknesses, n and k spectra and energy band gap of ultra-thin and ultra-thick films comprising single-layer and multi-layer film stacks. films can be deposited on either rough or smooth surfaces." n&k's scatterometers accurately and repeatably determine depth, cd, and profiles of simple and complex trenches and contact holes, with small or large pitches. in addition, n&k scatterometers measure ultra-thin films incorporated in such 2-d and 3-d structures; plus n&k scatterometers measure structures with high aspect ratios, as well as epi-silicon layer
