Abstract(in English) | Self-aligned passivation procedure for on chip copper interconnection has been developed to improve oxidation resistance. Al-Cu inter metallic compound was formed on copper wire by the annealing at 350C. The unreacted aluminum on SiO2 was selectively removed by a phosphoric acid treatment. Additional annealing in the gaseous mixture of H2 and O2 improved oxidation resistance of the passivation alloy. The increase in the resistance of the passivated copper wire pattern was also about 5%. The adhesion strength of plasma CVD SiO_2 on the copper was also improved by this method. |
