HILLSBORO, OR & RICHARDSON, TX (USA) – May 8, 2009 – TriQuint Semiconductor (Nasdaq: TQNT), a leading RF product manufacturer and foundry services provider, has been accredited by the Department of Defense (DoD) as a Category 1A ‘Trusted Foundry’ for its 100mm gallium arsenide (GaAs) facilities in Richardson, TX. Accreditation expands TriQuint’s wide-ranging GaAs circuit fabrication capabilities by including classified programs; a Category 1A designation is the highest awarded by the DoD.

DoD accreditation certifies that TriQuint processes meet stringent product control and secure handling standards during all stages of circuit fabrication. Accreditation also creates an avenue for increased high security MMIC (monolithic microwave integrated circuit) business, according to TriQuint Director of Defense and Aerospace Product Marketing, Dr. Gailon Brehm.

“This is a major accomplishment,” said Dr. Brehm. “TriQuint’s foundry has become one of a very elite group of trusted manufacturers that can fabricate both classified and unclassified circuits for critical DoD programs. This creates an opportunity for new business at TriQuint with government programs that only work with ‘trusted’ foundries. Accreditation builds on our heritage as a leading provider of high power, high frequency devices for defense and aerospace systems.”

Accreditation through the Trusted Access Program Office (TAPO) and the DoD’s Defense Microelectronics Activity (DMEA) requires following stringent policies and procedures regarding ‘chain of custody’ during manufacturing. These processes and TriQuint’s ability to fully satisfy the requirements are safeguards against supply chain interruption, modification or tampering with devices as well as unauthorized reverse engineering.

TriQuint is also recognized by Strategy Analytics¹ as the world’s largest commercial GaAs foundry. TriQuint’s 150mm commercial wafer fabrication takes place at its headquarters’ facility in Hillsboro, Oregon. TriQuint’s DoD-accredited 100mm GaAs wafer fabrication facility in Texas also serves commercial customers with a wide range of processes. Accreditation, combined with large-scale commercial capability in both Oregon and Texas, helps assure customers of quality, service, security and supply continuity for all levels of GaAs circuit fabrication.
