EXHIBIT 99.1 PRESS RELEASE ISSUED ON FEBRUARY 2, 2004

TOWER SEMICONDUCTOR LTD. ANNOUNCES FOURTH QUARTER AND YEAR-END 2003 RESULTS MIGDAL HAEMEK, Israel - February 2, 2004. Tower Semiconductor Ltd. (NASDAQ: TSEM; TASE: TSEM) today announced results for the fourth quarter and 12 months ended December 31, 2003. Revenues for the fourth quarter of 2003 were $19.8 million, an increase of 23 percent over revenues of $16.1 million in the prior quarter. In the fourth quarter of 2002, the company reported revenues of $15.6 million, including $4.0 million from a technology-related agreement. Total fourth quarter loss was $ 46.0 million, or $0.91 per share, compared with a loss of $37.1 million, or $0.77 per share, for the third quarter of 2003 and a loss of $13.6 million, or $0.33 per share, in the fourth quarter of 2002. The increased loss in the fourth and third quarters of 2003, as compared to the respective period of 2002, results mainly from the commencement of Fab 2 depreciation and amortization expenses, which were $20.0 million and $17.3 million for the fourth and third quarters of 2003, respectively. Revenues for the 12 months ended December 31, 2003 were $61.4 million, compared with revenues of $51.8 million for the 12 months ended December 31, 2002, which included $8.1 million from a technology-related agreement. The company reported a loss of $114.3 million, or $2.40 per share, for the 12 months ended December 31, 2003, compared with a loss of $51.4 million, or $1.63 per share in the 12 months ended December 31, 2002. The increased loss resulted primarily from the commencement of Fab 2 depreciation and amortization expenses, which totaled $37.3 million for the 12 months ended December 31, 2003. The company expects Q-1 2004 consolidated revenues to be in the range of $23 million and $25 million. Depreciation expenses for that period are expected to be in the range of $26 million and $28 million. "Strong demand from our Fab 2 existing and new customers enables us to continue to focus on our ramp execution," said Carmel Vernia, Tower's chairman and chief executive officer. "By December 31, 2003, Fab 2 had installed equipment capacity of 8,500 wafer starts per month using 0.18-micron process technology. We currently expect to have installed equipment capacity of between 13,000 and 15,000 wafers per month by the end of 2004."

"Our Fab 2 financing package with our banks and major investors was completed, as well as our underwritten equity offering of 11 million of our ordinary shares at a price to the public of $7.00 per share. With these financing deals behind us, we can now focus on our business operations," continued Vernia. "In addition, Fab 1 had positive cash flow from operations for the seventh consecutive quarter. The memorandum of understanding recently signed with Siliconix calls for placing orders valued at approximately $200 million for the purchase of products to be manufactured in Fab 1 over a seven to ten years period." During January the company's share count increased mainly as a result of the follow-on public offering and issuance of 2.3 million shares to its strategic partners in connection with the final payment of Fab 2's fifth milestone, at $7 per share. The number of Tower's outstanding shares as of February 2, 2004 is 65,137,883.
