I have a dicing problem question. I do not know where the Pt dust particles came from. I believe that they came after we diced the Pt/Ti/SiO2/Si wafer. How should we clean the wafer? I was thinking about using excessive use of DI water. Do you have a better idea? Thank you, Joseph Y. Lee Senior Engineer SAMSUNG ELECTRO-MECHANICS CO., LTD.
