Rapid thermal anneal of hydrogen-implanted metal-silicon nitride-silicon dioxide-silicon structure

Abstract
A post‐implant rapid thermal annealing technique is proposed to achieve very low interface trap density (10/eV cm2) at the SiO2‐Si interface in a metal‐Si3N4‐SiO2‐Si structure. The constitution of a donor layer induced by implanted hydrogen is explained with the aid of a model that predicts the formation of SiH groups. The proposed model is substantiated by comparing the IR data for furnace and rapid thermal annealed samples.
