TowerJazz Awarded Five-Year Multi-Million Dollar Foundry Improvement and

Sustainability Program in Partnership with US Air Force

Technology Investment Agreement focused on support of Air Force’s Large Die

ROIC Program and continued improvements for TowerJazz’s US facility

NEWPORT BEACH, Calif., – January 29, 2014 – TowerJazz has announced the award and program kick-off of a Technology Investment Agreement (TIA) with the United States Air Force/Air Force Research Laboratory (USAF/AFRL) of the Wright-Paterson Air Force Base.   The Defense Production Act Title III program is a five-year multi-million dollar Large Format Read Out Integrated Circuit (ROIC) Foundry Improvement and Sustainability program focused on continued technology and manufacturing leadership and improvements for TowerJazz’s Newport Beach, CA wafer fabrication facility in support of TowerJazz's overall aerospace and defense offering and customers. TowerJazz is a leading manufacturer of state-of-the art ROICs which are key elements in many commercial and military detectors, sensors, and imaging systems spanning air, land, sea and space. This award will enhance TowerJazz's ability to support production requirements of increasingly complex future ROIC designs.

TowerJazz continues to expand CMOS production for ROICs used in imaging arrays in both un-cooled and cooled applications in support of increased demand spanning 0.5-micron to 0.18-micron technology nodes. The five year program with the Title III Office will focus on the most advanced 0.18-micron CMOS process based large-die, stitched ROICs. In the 0.18-micron node, TowerJazz is making available to its ROIC customers its 1.8V/3.3V or 1.8V/5V dual gate oxide processes in a variety of substrate options such as bulk, epi and thick film SOI and with a wide range of desirable mixed-signal features from its commercial technology including high density linear MIM capacitors, precision resistors with triple well isolation and bipolar elements. TowerJazz also provides cryogenic models for its devices ensuring a high degree of confidence in the first time success of cooled ROIC designs.

TowerJazz operates a full on-shore facility with ITAR mask suppliers continuing a tradition started over 20 years ago when this facility was the primary semiconductor manufacturing site for Rockwell International.  In addition to supporting the manufacture of ITAR designs, TowerJazz is now also able to offer Trusted Solutions through Jazz Semiconductor Trusted Foundry.

“TowerJazz is extremely excited to have this opportunity to partner with Wright-Patterson AFB in support of the Air Force’s Large Die ROIC foundry improvement and sustainability program. This program will leverage past and ongoing accomplishments at TowerJazz in support of on-shore fabrication critical to our National Defense and assist in enabling the next generation of essential Aerospace and Defense applications,” said Mike Scott, Director, USA Aerospace and Defense Division, TowerJazz.
