             TOWER SEMICONDUCTOR ACHIEVES ISO/TS 16949 CERTIFICATION
                          FOR QUALITY MANAGEMENT SYSTEM

        Foundry Extends Its Quality Assurance to the Automotive Industry

MIGDAL HAEMEK, ISRAEL - NOVEMBER 30, 2005 - Tower Semiconductor, Ltd., a
pure-play independent specialty wafer foundry (NASDAQ: TSEM; TASE: TSEM), today
announced it has achieved ISO/TS 16949 certification from the highly respected
UK-based NQA (National Quality Association). This quality management system
standard certification covers all of Tower's departments and activities. The
certification is further evidence of the company's commitment to tight control
of its manufacturing processes, work procedures, and product performance,
including adherence to the demanding requirements of the automotive industry.

ISO/TS 16949 is currently the industry's most stringent quality management
system standard for the automotive industry.

The Standard Institute of Israel (SII) thoroughly audited Tower's quality
systems and programs for the certification. "The results of our certification
audit place Tower among the top Israeli organizations that were audited and
certified for ISO/TS 16949," said Ziva Patir, general manager of SII.

"Our ISO/TS 16949 certification is testimony to Tower's commitment to
maintaining and continuously improving quality and performance standards that
benefit all of our partners and customers," said Erez Taoz, senior vice
president, Operations of Tower Semiconductor. "Achieving it is an important
milestone in our strategic roadmap as we grow our offering within the specialty
fields of automotive mixed signal, image sensors and embedded NVM content of
microcontrollers."

ABOUT ISO/TS 16949

The ISO/TS 16949 standard is a technical specification defining quality system
requirements for the design and development, production, installation and
servicing of automotive-related products. The standard encourages the use of a
process approach that is aimed at improving process efficiency and is designed
to achieve the highest levels of product quality, productivity, competitiveness,
and continual improvement.

ISO/TS 16949 was jointly developed by the International Automotive Task Force
(IATF) members and approved by the International Organization for
Standardization. IATF members include leading automotive manufacturers and their
trade associations. This standard, together with any customer-specific
requirements, defines the quality system requirements used in the automotive
supply chain.

ISO/TS 16949 is based on ISO 9001:2000, but it includes a number of additional
specific quality requirements.
