摘要
Many types of defects arise from the copper CMP step, and careful inspection and an understanding of the failure mechanisms allow processes to be modified to reduce the defect levels. Some of the defects that appear at copper CMP actually come from previous process steps, so the right inspection and analysis approach can improve entire process modules.
