Counterfeit Prevention

Counterfeit microcircuits are an ever-increasing threat to complex weapon systems. When microcircuits are no longer available from the original manufacturer, or its authorized distributors, parts may only be available on the gray market. At this point the supply chain is susceptible to the insertion of counterfeit parts with limited part provenance. Counterfeits can include unauthorized…

The Obsolescence Problem

Early U.S. defense requirements were the driving force in the semiconductor industry and weapon systems were designed and manufactured using state-of-the-art microcircuits. These microcircuits were made to a strict set of military specifications designed to last for decades. As the consumer electronics industry has grown during the last quarter-century, the defense sector has been eclipsed…

Clearance and Security

In 2007 the DoD accredited SRI’s wafer foundry as a Department of Defense (DoD) Category 1 Trusted Foundry. With this endorsement, SRI is able to offer the DoD and Government agencies a secure on-shore, QML-certified wafer foundry for military electronics. SRI International has a TOP SECRET facility clearance and safeguarding capability (CAGE Code 0DKS7). Secure…
