NEWS ANNOUNCEMENT FOR IMMEDIATE RELEASE

 TowerJazz Announces the Availability of its Newly Released Advanced

Stacked BSI Hybrid Bonding Technology

Manufactured in Company’s advanced 65nm 300mm Uozu, Japan facility

New offering enables outstanding pixel performance and significant competitive advantages for leading growing

markets including automotive, event-driven sensors and high-end photography among others

MIGDAL HAEMEK, Israel, September 25, 2019 – TowerJazz (NASDAQ/TASE: TSEM), the global specialty foundry leader, today announced the release of its highly advanced 65nm stacked BSI hybrid bonding technology manufactured in Company’s 300mm facility in Uozu, Japan. This new offering, implemented in pixel level, enables a significantly reduced pixel size along with enhanced performance by splitting the pixel IC functionality between two wafers. With a pitch smaller than 4µm, sensors manufactured with this technology provide higher data rate, lower power consumption, better performance, and smaller form factor, accurately meeting the innovative requirements of world-leading growing markets and applications including automotive, high-end photography, event-driven sensors and Time of Flight (ToF), among others.

“We are very pleased to announce this new and highly advanced offering, providing our customers with extensive technological solutions which enable them to competitively lead in their markets,” said Dr. Avi Strum, senior vice president and general manager of the Sensor Business Unit at TowerJazz. “As always, we are greatly committed to bring to market the most advanced technology and state-of-the-art pixel performance providing strategic, value-add development opportunities and roadmap”.

With pixel functionality split between wafers, TowerJazz hybrid BSI stacking, electrically connects each of the Photo Diodes (PD) in the imaging top wafer to the pixel circuit in the bottom wafer. This new offering is an expansion of the Company’s well-established and reputable CIS technology which includes stitching with 1D and 2D for large format sensors in the high-end photography, industrial and medical X-Ray markets, as well as highly advanced SPAD technology profoundly used in the rapidly growing automotive market with silicon proven pixels that can be customized to customer specifications.

In addition, TowerJazz has recently expanded its non-imaging sensor (NIS) technology platform portfolio serving diversified market segments. Thesilicon based sensors are embedded on the Company’s mature and well-established 180nm CMOS manufacturing process and now include full system-on-chip, and unique environmental sensor technology for gas, temperature and time-to-temperature sensing, radiation and magnetic sensing, in addition to a GaN based platform for high-temperature sensing applications. TowerJazz NIS platform offers complimentary design IPs and PDKs enabling design support and fast time-to-market.

Dr. Avi Strum will give a keynote presentation at the upcoming MEMS & Imaging Sensor Summit to be held in Grenoble, France on Sept. 25-27, 2019. The presentation, titled: Considerations of Optical Fingerprint and 3D Face Recognition Sensors for Cellular Security Applications, is scheduled for Sept. 25th 5:30pm-6:00pm as part of the summit’s opening session.
