Exhibit 2 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. About Tower Semiconductor Ltd.

Exhibit 4 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."
