7 The raw materials are firstly crushed and made into powdered form and stored in silos The clay is then washed in washing mills to remove adhering organic matters found in clay The powdered limestone and water washed clay are sent to flow in the channels and transfer to grinding mills where they are completely mixed and the paste is formed known as slurry

Ultra thin wafer technology and applications A review

Though the difference between the DBG process and the standard back grinding process is just the process sequence ultra thin wafer state actually does not exist in DBG process due to the formation of separated die when the wafer is thinned Thus the dicing speed could be increased due to the reduction of backside chipping risk and the
