Abstract
A system is disclosed for providing backward and forward traceability by a methodology which identifies discrete components (die, substrate and/or passives) that are included in a semiconductor device. The present technology further includes a system for generating a unique identifier and marking a semiconductor device with the unique identifier enabling the semiconductor device, and the discrete components within that device, to be tracked and traced through each process and test in the production of the semiconductor device.
