发明名称 MARKING METHOD FOR WAFER DICE
摘要 Disclosed is a method for marking, by using a laser marker, a plurality of wafer dice divided by a wafer dicing process. The disclosed marking method for wafer dice comprises the steps of: setting a plurality of scan regions having a mutually overlapping portion on a wafer including the wafer dice; scanning the scan regions of the wafer a plurality of times by using a line scan camera; collecting position information of each of wafer dice located in regions in which the scan regions do not overlap; collecting, through image synthesis, position information of each of wafer dice located in regions in which the scan regions overlap; and marking, by using the laser marker, each of all the wafer dice of which the position information has been collected.
