Abstract

The authors have investigated the effect of phonon-energy-coupling enhancement induced by rapid thermal processing (RTP) and deuterium annealing on the leakage current characteristics of HfSiON gate dielectrics. The leakage current is reduced by one- and-a-half orders of magnitude after RTP and deuterium annealing of HfSiON gate dielectrics. The leakage current density of the HfSiON gate insulator with equivalent oxide thickness of 5.2 Å was only 4× 10-2 A cm-2. This suggests that HfSiON with the enhanced phonon-energy coupling can be scaled down to below 5 Å.
