没有一种有效的方法能够完全消除划伤
) Abstract: Micro-scratch is a major defect for oxide CMP(including STI/ILD/IMD CMP), serious micro-scratch would form W Puddle, which will make metal short and then cause yield loss
So far no robust method can avoid this issue
Based on P-FMEA theory, do improvement at severity, detection and occurrence three aspects: add process time at post WCMP to decrease micro-scratch impact, making a robust monitor control method to robust detect this issue early and study a method to decreasing the occurrence of this issue
By all of the efforts, Micro-scratch issue at CMP process has much improvement
