发明名称 Process for chemically mechanically polishing wafers
摘要 The invention relates to a process for chemically mechanically polishing and grinding wafers. The CMP slurry that is used for grinding is analyzed using slurry atomic absorption spectroscopy. This allows rapid and sensitive analysis of the slurry constituents, in particular of interfering ions. The process can be automated and makes it possible to process wafers with a constant quality. Furthermore, rapid fault analysis or optimization of the process parameters used during the grinding is possible.
