| Abstract: | Mechanism of copper interconnection CMP in ULSI was studied. The factors such as polish conditions, methods and consumptions which affected polish speed and surface state were analyzed. Specially aiming at the effect of polish slurry on copper chemical-mechanical polish, the primal problems existed at present were brought forward, and the prospect of research direction and content in future were presented. |
