TOWER SEMICONDUCTOR LTD. ANNOUNCES FIRST QUARTER 2004 RESULTS

Wednesday April 28, 8:00 am ET

REVENUES INCREASED BY 116 PERCENT YEAR OVER YEAR AND 37 PERCENT QUARTER TO
QUARTER

MIGDAL HAEMEK, Israel--(BUSINESS WIRE)--April 28, 2004--Tower Semiconductor Ltd.
(NASDAQ: TSEM; TASE: TSEM) today announced results for the first quarter ended
March 31, 2004.

Revenues for the first fiscal quarter were $27.2 million, an increase of 116
percent over revenues of $12.6 million in the first quarter of 2003, and an
increase of 37 percent over prior-quarter revenues of $19.8 million.

Loss for the quarter was $38.5 million, or $0.61 per share. That compares with a
loss of $46.0 million, or $0.91 per share, sequentially and a loss of $14.4
million, or $0.33 per share in the same quarter last year. The increase in loss,
as compared with the first quarter of 2003, is primarily attributed to the
commencement of Fab 2 depreciation and amortization on Q-3 2003.

The company expects the current quarter's revenues to be in the range of $33
million and $36 million.

"I am very pleased with our performance, which is in line with our plans," said
Carmel Vernia, Tower's chairman and chief executive officer. "Fab 2 is
demonstrating rapid revenues growth and we begin to see the results of its prior
years' heavy investments. Fab 1's utilization is on the rise as well, and I'm
glad to report it returned to profitability in Q-1 2004. Both fabs are winning
new designs in prototyping and early-production activities for new and existing
customers. Overall I am confident we have the infrastructure and organization in
place to leverage the global upturn in the semiconductor industry into a
successful business."

Tower will host a conference call to discuss these results on Wednesday, April
28, 2004 at 11:00 a.m. Eastern time / 18:00 Israel time. To participate, call
1-800-289-0543 (U.S. toll-free number) or 1-913-981-5526 (international) and

03-925-5910. The conference call also will be Web cast live at

both Web sites for replay for 90 days.
