发明名称 METHOD FOR PROCESSING WAFER
摘要 The present invention provides a method which includes sticking a surface protection sheet for dicing onto a surface of a wafer and cutting the sheet together with the wafer to protect the surface of the wafer from being contaminated by deposition of a dust such as swarf and the like, and picking up a chip without causing cracking or chipping in the chip after a dicing step, in the steps of dicing the wafer and then picking up the chip. The method includes: sticking the surface protection sheet for dicing onto the surface of the wafer; cutting the sheet together with the wafer; subsequently giving a stimulus to the surface protection sheet for dicing to peel the end of the chip from the dicing tape; and then picking up the chip.
