Abstract
Semiconductor device identification using quantum dot technology. A semiconductor nanocrystal based target is fabricated. A guard ring superjacent the fluorescing surface of the nanocrystal surface is provided to ensure repeatability of spectral mapping and analysis data. A transparent cap on the target may enhance performance. A system for coding a semiconductor device is described. A method is described for fabricating quantum dot targets in a methodology compatible with subsequent semiconductor fabrication process steps.
