Abstract:

The incorporation of nitrogen and SiN capping layer onto HfO 2 dielectrics by plasma processing enhanced the electrical performance of poly integrated high k gate stacks with reduced gate leakage and improved EOT scalability. A 5 Å CVD SiN layer on HfO 2 was demonstrated to improve significantly poly- HfO 2 device yield (>95% at 1E-4 cm 2 ) with no change of electrical thickness.
