 TOWER SEMICONDUCTOR LTD. ANNOUNCES SECOND QUARTER AND SIX MONTHS 2004 RESULTS

             Quarterly Revenues Increased 161 Percent Year-Over-Year
                           and 24 Percent Sequentially

MIGDAL HAEMEK, Israel - July 21, 2004 - Tower Semiconductor Ltd. (NASDAQ: TSEM;
TASE: TSEM) today announced results for the second quarter and six months ended
June 30, 2004.

Revenues for the second quarter of 2004 totaled $33.7 million, an increase of
161 percent over $12.9 million reported in the second quarter of 2003 and an
increase of 24 percent over revenues of $27.2 million in the first quarter of
2004.

The loss in the second quarter narrowed to $36.5 million, or $0.55 per share,
compared to a loss of $38.5 million, or $0.61 per share, for the first quarter
of the year. In the second quarter of 2003 the company reported a net loss of
$16.8 million, or $0.37 per share.

Revenues for the six months ended June 30, 2004, were $60.9 million, an increase
of 139 percent over revenues of $25.5 million for the six months ended June 30,
2003. The company reported a loss of $75.0 million, or $1.16 per share, compared
with a loss of $31.2 million, or $0.70 per share, in the six months ended June
30, 2003.

Tower said the second quarter and first half losses reflect the high investment
made in Fab 2 and its resulting depreciation, and that it is on course toward
positive EBITDA by year-end. The company expects Q-3 2004 revenues to be in the
range of $35 million and $38 million.

"I am very pleased that we were able to achieve our performance goals this
quarter for both Fab 1 and Fab 2," said Carmel Vernia, Tower's chairman and
chief executive officer. "Fab 1 is profitable, and its utilization continues to
increase. Fab 2 is still expected to reach 14,000 installed capacity by year-end
and we continue to experience higher demand than our current installed capacity
from virtually all markets, especially for consumer devices, which results in
strong revenue growth."

"Progress was also made in our specialized technologies, with the receipt of our
first customer commitment for 0.18-micron embedded flash. Additionally, we
shipped first product samples of 0.18-micron CMOS image sensors to two customers
and started development work for the RFID tag market, combining our know how and
expertise in two of our specialized areas - embedded NVM and mixed signal
technologies. We have also continued to execute per plan on our 0.13-micron
technology transfer and infrastructure activities."

During the second quarter, the company received a Gold Supplier award for the
fifth-consecutive year from Freescale Semiconductor Inc., a subsidiary of
Motorola Inc.

Tower will host a conference call to discuss these results on Wednesday, July
21, 2004 at 11:00 a.m. Eastern time / 18:00 Israel time. To participate, call
