ABSTRACT
For the evaluation and characterization of Atomic Layer Chemical Vapour Deposition ALCVD™ high k dielectrics we have used a KLA-Tencor, Quantox in-line electrical metrology tool. We have investigated and found that the Quantox tool can be used as a fast and much less expensive evaluation tool for optimization of ALCVD process conditions and process stability monitoring. Equivalent Oxide Thickness (EOT) obtained from Quantox agrees very well with High Frequency Capacitance- Voltage, C-V, results
