TowerJazz Announces New Design Center Partnership Incentive Program

MIGDAL HA’EMEK, Israel, and NEWPORT BEACH, Calif., May 31, 2011 —TowerJazz, the global specialty foundry leader, today announced its “Design Star Awards Program,” a new design center partnership incentive program offered to independent design centers. The program will encourage design centers that enroll in this program to refer new customers and new products to TowerJazz. This will increase TowerJazz’s IP portfolio, specifically increasing the number of specialty designs taped into TowerJazz, thereby strengthening TowerJazz’s position as the leading specialty foundry.  In turn, these design partners will receive benefits from TowerJazz on products and services ordered either by such design partners or their customers.

Aligned with TowerJazz’s position as a specialty foundry, the independent design centers are encouraged under the incentive program to refer their customers to manufacture products using TowerJazz specialty technologies such as RF/high performance analog, power management, CMOS image sensor, mixed-signal and MEMS as their preferred platform.

The TowerJazz Design Star Awards Program offers three levels of partnership: platinum, gold and silver.  For each TowerJazz product or service ordered under this program, points are accrued and criteria are defined regarding participation at each level. The design partners can redeem their points against mask-sets, proto-lots, MPW or other engineering services.

“Our Design Star Awards Program benefits TowerJazz design partners and is a two-way stream; they will encourage their customers to manufacture products at TowerJazz and we will recommend our customers to design their products with our design partners,” said Ori Galzur, TowerJazz Vice President of Design Center and PDK Development.  “This is a win-win program not only for our design partners and TowerJazz, but also for our mutual customers as they will benefit from best-in-class design and manufacturing services.”

TowerJazz will be exhibiting (booth #2024) at the Design Automation Conference (DAC) June 6-8, 2011 at the Convention Center in San Diego, CA and will present its new Design Star Awards Program.  For more information, please contact: Limor Levy-Kendler, Director of Design Services and IP, at +972-9-8636367 or limor.levykendler@towerjazz.com.
