Overview

The QS2200 and QS3300 are Fourier-Transform Infra-Red spectrometers designed for non-destructive wafer analysis. These systems are used for the characterization and measurement of semiconductor substrates as well as in device manufacturing. The QS3300 is a production version which supports high-volume 300mm manufacturing for various applications: boron and phosphorus concentration in BPSG films, atomic hydrogen concentrations in silicon nitride passivation layers, fluorine in FSG films, epitaxial thickness, concentrations of interstitial oxygen and substitutional carbon in silicon.
