发明名称 Method of dicing wafer using plasma
摘要 Provided is a method of dicing a wafer that is thin and includes a low-K material using plasma without causing chipping and cracking during sawing without using an etch mask and without performing a separate wafer coating process. The method includes recognizing scribe lines of a front side of the wafer by using an image recognizing unit to obtain recognition information, performing two etching processes, wherein at least one includes plasma etching, on a backside of the wafer by using the recognition information to separate the wafer into a plurality of semiconductor chips, and adhering the plurality of semiconductor chips to an extended tape or a die attach film.
