摘要： High through-put Cu CMP is achieved with reduced erosion and dishing by a multi-step polishing technique. Deposited Cu is polished with fixed abrasive polishing pads initially at a high removal rate and subsequently at a reduced removal rate and high Cu:barrier layer (Ta) selectivity. Embodiments of the present invention include reducing dishing by: controlling platen rotating speeds; increasing the concentration of active chemicals; and cleaning the polishing pads between wafers. Embodiments also include removing particulate material during CMP by increasing the flow rate of the chemical agent or controlling the static etching rate between about 100 Å and about 150 Å per minute, and recycling the chemical agent. Embodiments further include flowing an inhibitor across the wafer surface after each CMP step to reduce the static etching rate.

摘要： The useful lifetime of a fixed abrasive article is extended and wafer-to-wafer uniformity enhanced by preconditioning a fixed abrasive element and/or periodic conditioning after initial wafer polishing. Embodiments include preconditioning by forced removal of an upper binder-rich portion of the fixed abrasive elements to expose abrasive particles having a similar concentration as the bulk concentration at about one half the height of the elements. Embodiments further include periodic conditioning after initial wafer polishing by forced removal of an upper portion of the fixed abrasive elements.
