摘要

CMP technology is a key factor for planarization of ILD, plug and interconnection. Cu dual damascene with a combination of low-k ILD becomes a major structure for multi-level interconnection. CMP tool is now in a second generation and is entering into a third generation. Cu CMP process has still many problems to solve, however, there has been a progress in Cu slurry and post cleaning.
