The Influence of NH3 Anneal on the Crystallization Kinetics of HfO2 Gate Dielectric Films



Patrick S. Lysaght, Joseph Woicik, Brendan Foran, Joel Barnett, Gennadi Bersuker, B H. Lee


HfO2 gate dielectric thin films have been exposed to anneal processing in NH3 and N2 ambient in order to decouple the influence of N incorporation from that of the thermal cycle alone. We report on the effectiveness of NH3 processing to introduce N into the dielectric film system and characterize the local coordination and crystallization kinetics that give rise to the resultant high-k film microstructure as determined from a variety of high resolution spectroscopic and imaging analysis techniques.
