Tower Semiconductor's Authorized Design Center Program Achieves a New Silicon
Migration Success

Tuesday March 9, 7:30 am ET

Smaller Die Size, Improved Performance and Higher Yields Realized Through
Tower's Partnership With Sycon Design

MIGDAL HAEMEK, Israel--(BUSINESS WIRE)--March 9, 2004-- Tower Semiconductor Ltd.
(Nasdaq:TSEM - News; TASE:TSEM) today announced the new migration of a complex
high-performance, custom integrated circuit device. The device was designed by
Sycon Design Inc., a member of Tower Authorized Design Center program, for
Comtech AHA Corporation (CAC), a wholly owned subsidiary of Comtech
Telecommunications Corp. (Nasdaq:CMTL - News). Comtech AHA's forward-error
correction circuit (AHA4541) is the first Comtech AHA order manufactured using
Tower's 0.18-micron process technology in its Fab 2 production facility.

Sycon optimized the design for Tower's manufacturing process technology,
achieving:

     o    30% die size reduction

     o    Improvement of more than 100% in performance

     o    Considerably higher product yields over previous devices manufactured
          by a leading foundry's 0.18-micron technology.

"We were faced with an accelerated development timetable and demanding
functional requirements," said Bill Thomson, president of Comtech AHA
Corporation. "The teamwork with Tower Semiconductor and Sycon Design allowed us
to stay on schedule, and surpass our performance and quality targets with
state-of-the-art technology and design expertise. The partnership for this
migration strengthened our business relationship with Tower, which has seen more
than 10 years of successful cooperation utilizing Tower's Fab 1 technologies."

The AHA4541 is designed for use in applications that require very high data
rates, and has demonstrated bandwidth efficiency with stringent data reliability
requirements.

"Our experienced design team has a proven track record of improving chip
performance and delivering complex designs on time," said Sharon Zohar,
president, chief executive officer and founder of Sycon Design. "As a Tower
Authorized Design Center, we offer extensive experience with Tower's process
flows and intellectual property, enabling quick, cost-effective physical design
implementation with superior results."

"The first-time silicon success of the Comtech AHA demanding project,
demonstrates the effectiveness of Tower's quality and reliability systems,
incorporated with Tower's Authorized Design Center Program," said Doron Simon,
vice president of marketing and president of Tower USA, "As a result, our
customer enjoys high performance and yield, die size reduction and reduced time
to market."

Tower Semiconductor Expedites Production of Mixed-Signal Integrated Circuit for
Smart Link

Monday February 23, 7:22 am ET

Record Time for Initial Production from Prototyping

MIGDAL HAEMEK & NETANYA, Israel--(BUSINESS WIRE)--Feb. 23, 2004--Tower
Semiconductor (NASDAQ: TSEM; TASE: TSEM) has launched production of a
Coder-Decoder (CODEC) integrated circuit (IC) for Smart Link, Ltd., a leading
developer and supplier of modem solutions for the communications industry. With
an initial production order released already and forecasted orders of few
million dice, this production marks the opportunity for a long term relationship
between Tower and Smart Link. Utilizing 0.18-micron, mixed-signal technology in
its Fab 2 facility, Tower's prototype process enabled the successful development
of Smart Link's SL2800B (Raptor). Tower began producing the SL2800B (Raptor) ICs
shortly after prototyping began, utilizing Tower's Shuttle program. Factors
essential to the acceleration of production were the simultaneous implementation
of the intellectual property (IP) block with the packaging and testing of the
first batch of ICs.

Avnet ASIC Israel and Chipidea, participants in Tower's Authorized Design Center
program (TADC), helped to achieve first silicon quickly and efficiently.
Chipidea provided the mixed signal IP, and Avnet ASIC Israel provided design
kits, libraries and other manufacturing tools. Avnet has also integrated the IP
and Smart Link logic design and performed Place and Route, Test Vector
Generation and Tape Out according to Tower's Design Rules.


"The Smart Link project demonstrates Tower's ability to accelerate the time from
project kick-off to production, helping customers achieve exceptional
time-to-market," said Danny Hacohen, Tower's vice president of sales for Europe
and Asia. "Tower's leadership in mixed-signal execution and close work with its
customer and design partners lead to first-time silicon production with maximum
efficiency."


"Smart Link benefits greatly from the combined resources of Avnet, ChipIdea and
Tower," said Moty Mebel co-founder and CEO of Smart Link "The partnership made
the production and verification of our device possible in a quick and highly
efficient manner, and we look forward to future projects executed with the same
ease and cooperative spirit."


Tower's Authorized Design Center program was launched in September 2003 to help
customers accelerate the design-to-silicon process and enhance first-time
silicon success. Chipmakers, particularly fabless companies, can augment their
own design resources with the specialized design capabilities of
Tower-authorized design centers. By working with the design centers, chipmakers
can create integrated circuit designs optimized for Tower's manufacturing
process technologies. Authorized design centers are capable of designing both
complete integrated circuits and embedded IP blocks.

Tower Semiconductor Receives Environmental Management Certification

Monday February 9, 7:30 am ET

ISO 14001 endorsement demonstrates commitment to highest standards for customers
and environment

MIGDAL HAEMEK, Israel--(BUSINESS WIRE)--Feb. 9, 2004-- In conjunction with its
corporate environmental management initiative, Tower Semiconductor Ltd. (NASDAQ:
TSEM - News; TASE: TSEM) has received ISO 14001 certification from The Standards
Institution of Israel.

A series of international standards on environmental management, ISO 14000
provides a framework for the development of an environmental management system
and the supporting audit program. ISO 14001 is the cornerstone standard of the
ISO 14000 series. It specifies a framework of control for an environmental
management system against which an organization can be certified by a third
party.


"Qualifying for ISO 14001 certification represents Tower's involvement and
interest in its surrounding community as well as in its customer requirements,"
said Ziv Hilleli, quality system director at Tower Semiconductor. "As a global
citizen, Tower must be aware of all environmental implications, and we must take
all necessary measures to eliminate any negative impact. We are fully committed
to implementing ISO 14001 principles to achieve continuous improvement in all
environmental aspects."


"I am very proud that Tower, the leading semiconductor foundry in Israel, is
implementing the ISO 14000 standard," said Ziva Patir, general director of The
Standards Institution of Israel. "This standard is most important for promoting
a policy of environmental management. All companies that implement the standard
promote environmental quality in their respective activities and in modern
society in general. There is no doubt," added Mrs. Patir, "that this standard
reflects the close interrelationship between the business community and the
quality of life in our modern world."


The ISO 14001 certification applies to all Tower manufacturing facilities,
including Fab 1 and the highly advanced Fab 2, where leading-edge semiconductor
devices with 0.18-micron and lower geometries are being manufactured. The
company's design center in Netanya, Israel received certification, as well.


In other environmental news, Tower Semiconductor was awarded the Sony Green
Partner certificate in December 2003. "This is a company-wide effort, and we are
all continually working together to meet standard requirements," said Rafi Nave,
vice president of customer service at Tower Semiconductor. "Our considerable
investment in quality management in general, and in environmental management in
particular, contributes to our success and continuous growth. We act responsibly
and respectfully in every aspect of our business - towards customers, suppliers
and the environment. We are honored to be recognized for our efforts."
