Scatterometers/ Thin Film Metrology Systems
LittleFoot Series - n&k Technology, Inc. (n&k Technology)
The n&k LittleFoot-CD, and LittleFoot-CD450 are DUV-Vis-NIR scatterometers/thin film metrology systems, based on polarized reflectance measurements (Rs and Rp) from 190nm to 1000nm, with microspot technology. The systems in the LittleFoot-CD Series determine thickness, n and k spectra from 190nm-1000nm of thin films, as well as depths, CDs, and profiles of trenches and contact holes.
