Abstract:
Otherwise-unused metal pads are utilized for mechanically marking an identification number on each chip in each reticle of each semiconductor wafer. A chip-specific marking pattern is scribed into selected metal pads using a standard commercial wafer probe controlled by a custom-built controller to direct the probe or probe stage to implement the pattern. Visual inspection (manual and automated) may then be used for die identification based on the probe-marked pattern, including incorporating the visual inspection of these pads into the product building process.

Claim (Index 21):
A method of encoding individual chips on a semiconductor wafer during fabrication, comprising:\n a) positioning the wafer on a probing stage; b) positioning a probe over the wafer; c) identifying designated metal pads on each chip on the semiconductor wafer for encoding, the designated metal pads comprising selected metal pads for marking and other metal pads to be left unmarked; d) scribing a selected metal pad by adjusting the position of the probe and/or the probing stage to bring the probe into contact with one of the selected metal pads on one of the chips, thereby scribing the selected metal pad with an identifiable mark; e) repeating step d) for each selected metal pad on the one chip; f) repeating steps d) and e) for each selected chip on the wafer.
