SEMI T20 - Specification for Authentication of Semiconductors and Related Products
This Standard was technically approved by the Traceability Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on December 4, 2015. Available at www.semiviews.org and www.semi.org in April 2016; originally published November 2008; previously published July 2010.
NOTICE: This Document was reapproved with minor editorial changes.
Assumed Commercial Environment
Large quantities of semiconductor device products are distributed in the business world to be embedded into various electronics products such as television sets, computers, automobiles or their components, and so on. The electronic component supply network is frequently contaminated by counterfeit and tainted product. The risk of procuring contaminated goods increases when authorized (certified) distribution networks run out of product. This may occur with supply shortfalls or terminated products. Then, purchasing policy may also force procurement from non-certified distributors.
Authentication of Distributed Products
A product may be substituted by counterfeiting the item secretly anywhere in a chain of distribution. If the product has specific identification; for example, an unpredictable random code, on it issued by some authentication organization, it can be determined whether it is genuine or not anywhere in the distribution chain.
When authentication is practiced consistently at key points in the trade stream, and when it is left open for any party to participate, it drives unintended counterfeit purchases to a minimum in a way that can be deployed easily and relatively inexpensively in a wide variety of settings.
Availability of Standards
The semiconductor industry has lacked standardized methods to validate the integrity of goods from non-certified distributors or suppliers. The purpose of this specification is to describe the system architecture aspect of an authentication process to establish the trusted identity of products or objects.
This Specification is the basic element of a suite of Standards aimed at enabling automated, reliable, and secure product authentication for the semiconductor industry, thereby reducing the presence of illegal counterfeit items in the marketplace.
This Specification covers structure, behavior, and services for the organizations and entities involved in authentication of semiconductor and related products or objects through the use of secure serialization.
