Overview

The ASET-F5x is a thin film metrology system that can measure materials across a continuous wavelength spectrum from 190 nm to 800 nm. It accurately measures complex multi-layer thin film stacks using spectroscopic ellipsometry and precisely measures advanced, ultra-thin gate dielectric films. It provides the accuracy, repeatability, and system-to-system matching required to monitor advanced ICs with geometries as small as 0.1 micron. Its applications include diffusion films/film deposition, CMP, lithography, and etch.
