发明名称 DBG system and method with adhesive layer severing
摘要 An array of grooves ( 23 ) is formed in a first side ( 12 ) of a wafer ( 10 ) during a wafer processing method. A back grinding tape ( 16 ) is adhered to the first side. An amount of material is removed from the second side ( 20 ) of the wafer. An adhesive layer ( 30 ) is applied to the second side. Dicing tape ( 24 ) is applied to the adhesive layer to create a first wafer assembly ( 32 ). The first wafer assembly is supported on a support surface ( 34 ) with the dicing tape facing the support surface and the back grinding tape exposed. The back grinding tape is removed and the adhesive layer is severed through the array of grooves to create individually removable die ( 28 ).
