Abstract
A complete optimisation of the copper CVD deposition was achieved with a bubbler delivery system. However the deposition rate was found to b e limited to 30 nm/min. With a DLI delivery system, a major improvemen t of the deposition rate 100 nm/min was achieved at high Cupraselect(R ) Bow rate with a void free deposition. The nucleation delay, the depo sition rate and the reproducibility were dramatically improved by wate r vapour addition. From the experimental results, an explanation has b een proposed for this effect.
