What SEMI Traceability Standards?

I have been involved for many years in the development of standards for the Semiconductor industry mainly under the umbrella of SEMI, our industry's standards body. Most recently I have been involved with the SEMI E142 standard as chairman of the Sort Map Task Force and SEMI T20 as Technical Architect (well one of them) of the Anti-Counterfeiting Task Force. These standards, among other things, enable single device tracking through assembly and the detection and prevention of counterfeit devices entering the supply chain. These standards then are the initial topic of this blog although it may morph and extend over time.
