Half-micron pitch Cu interconnections have been achieved by self-aligned plug (SAP), MOCVD-TiN barrier layer (MBL), and alumina capped oxidation-free structure (ACOS). Low resistance 0.12μm Cu interconnections whose effective resistivity is 1.9μΩcm have been obtained. Improved thermal stability up to 600°C has been achieved for quarter-micron Cu contacts. Cu oxidation has been suppressed without increasing resistance by using a trimethylaluminum (TMA) treatment.
