  • Method of sorting dies using discrimination region

    Abstract: A method of sorting dies using a discrimination region includes preparing a wafer including a chip region in which a plurality of dies are disposed and an edge region in which at least one discrimination region is disposed; testing the dies to prepare a wafer map for defining the coordinates of good dies and bad dies; allowing dies defined by the wafer map to correspond to the dies of the wafer; and confirming the correctness of the correspondence between the wafer and the wafer map by checking whether the discrimination region is included in the dies defined by the wafer map.
