Forza Silicon Announces Continued Strategic Partnership with TowerJazz

Partnership Combines Forza Silicon’s CMOS Image Sensor Design Expertise with TowerJazz’s

Specialty Process Technologies to Fulfill Customer Time-to-Market Requirements

Irvine, CA – November 13, 2013 – Forza Silicon Corporation, a fabless mixed-signal semiconductor company, and TowerJazz, the global specialty foundry, today announced at the TowerJazz 8th annual U.S. Technical Global Symposium, their continued strategic partnership to design and produce mixed-signal and image sensor chips utilizing TowerJazz’s process and design technology capabilities.

The announcement highlights an existing 11-year relationship between the two companies, during which Forza Silicon has successfully completed several developments employing TowerJazz’s processes. Recent developments include the following:

·   133 Mpixel, 60 FPS image sensor

·   Low power global shutter SOC imager

·   Family of sensors for dental X-ray

·   Small size endoscopy sensor

·   High-speed global shutter sensor

Forza Silicon designs custom CMOS image sensors, which comprises TowerJazz’s Advanced Photo Diode (APD) pixel IP, and utilizes its Fab2, 0.18-micron process technology. The APD technology used in these CMOS image sensors enables improved optical and electrical performance of ultra-small pixels utilizing deep sub-micron process technologies, thus enabling the manufacturing of small, cost-effective image sensor solutions.

“We joined TowerJazz’s Design Center Program several years ago and have seen significant efficiencies since we’ve aligned our business processes to meet the time-to-market requirements of our customers,” said Dr. Barmak Mansoorian, Forza Silicon President. “This partnership is a natural complement to our business model of providing end-to-end design engineering and manufacturing services from circuit design through to production testing.

“We are excited to work with partners such as Forza Silicon who have proven to be true innovators in the CMOS image sensor field,” said Dr. Avi Strum, VP & General Manager, CMOS Sensors Business Unit,VP Sales, Europe. “Forza Silicon’s great depth of talent and proven ability to work closely with a customer on an idea, collaborate on a design, and follow through to volume production is critical to deliver advanced solutions. Together, we are committed to producing innovative, cutting-edge products for a variety of applications.”
