ABSTRACT:
A die sorting apparatus for a wafer is provided that associates logical positions of each die from a map file for storing records of testing information based upon testing performed on individual dice comprised in the wafer with its physical position as illustrated by an image acquired by an image capturing device showing physical positions of the dice, after the dice have been singulated. A processing device can thus determine actual physical positions of the dice for reference by a die pick-up device configured to selectively pick up dice that meet predetermined criteria according to the testing information from their actual physical positions as determined.
