TowerJazz to Present Webinar on its Advanced Technologies for Manufacturing

Automotive Devices

Webinar to demonstrate TowerJazz’s alignment on the rising global trend of industry specifications for mass production of automotive

products

MIGDAL HAEMEK, Israel, February 26, 2015 – TowerJazz, the global specialty foundry leader, today announced it will host a webinar on March 3, 2015 to present a number of TowerJazz’s advanced automotive technologies, its Automotive Quality Policy, and share multiple examples of product qualification results accumulated by TowerJazz over many years. TowerJazz will demonstrate its alignment on industry specifications for automotive mass production from the foundry perspective. The webinar will cover TowerJazz’s reliability performance and world-class quality system implemented in its production facilities. The webinar targets fabless engineers, foundry interfaces and reliability managers working on the design, fabrication, and manufacturing of devices for the automotive industry.

In this webinar, TowerJazz will highlight wafer manufacturing processes for automotive applications which require a high grade of process and reliability performance, along with development and implementation of zero defect mentality in manufacturing procedures.  TowerJazz will provide guidelines for physical and environmental reliability qualification success that are different from those for non-automotive products. Several TowerJazz automotive technologies, from 0.60-micron to 45nm, that meet these targets will be presented.

TowerJazz will also present its Automotive Quality Policy and its in-field implementation. The quality policy includes automatic outgoing inspection, zero defect mentality methodology, Maverick Alert System, and more. Several examples of product qualification results, accumulated over many years of manufacturing automotive devices, will also be shared.

The automotive webinar will be held for 40 minutes including a 10-minute Q&A session and will be hosted by Dr. Eitan Shauly – Director of Integration, MS/CMOS BU and Michael Axelrod - Senior Staff Account Manager. Some prior knowledge or experience in manufacturing, device and reliability is required.

ISR Clock – 10:00am | UK – 08:00am | Shanghai – 15:00|  Tokyo – 16:00
