Abstract:
Systems and methods for visual identification of semiconductor dies are described. In some embodiments, a method may include: receiving a semiconductor wafer having a plurality of dies and printing a unique visual identification mark on each of the plurality of dies. In other embodiments, a method may include receiving an electronic device comprising a die and a package surrounding at least a portion of the die and reading, from the electronic device, a unique visual identification mark that encodes a Cartesian coordinate of the die relative to a reference point on a semiconductor wafer.
