Angle resolved XPS (ARXPS) is a powerful tool for the determination of the thickness of ultra-thin films. In the case of high-k dielectric layers, the technique is capable of measuring the thickness of both the high-k layer and intermediate layers of silicon dioxide or metal silicate. The values for layer thickness are in close agreement with those generated by a variety of other techniques. As well...
SiON gate dielectric is optimized for general purpose 65 nm node applications by using a first nitridation approach. A process parameter screening is done where the resulting SiON films are analyzed by angle resolved XPS and non-contact probing by Quantox. Good correlation between XPS and Quantox results are found. We demonstrate also correlation between Quantox results and transistor performance...
