                TOWER SEMICONDUCTOR FIRST QUARTER 2007 REVENUES
                      INCREASED 55 PERCENT YEAR-OVER-YEAR

       COMPANY MAINTAINS POSITIVE CASH FLOW FROM OPERATIONS AND POSITIVE
       EBITDA AND GUIDES FOR EIGHTH SEQUENTIAL QUARTER OF REVENUE GROWTH

MIGDAL HAEMEK, Israel - May 1, 2007 - Tower Semiconductor Ltd. (Nasdaq: TSEM,
TASE: TSEM), an independent specialty foundry, today announced first quarter
2007 financial results.

FINANCIAL HIGHLIGHTS:

     o    Reported quarterly revenues of $55.6 million, meeting previously
          stated guidance, and representing year-over-year growth of
          approximately 55 percent

     o    Recorded positive cash flow from operations for the second consecutive
          quarter and achieved positive EBITDA for the sixth consecutive quarter

     o    Expecting continued revenue growth in the second quarter of 2007 to be
          between $56 and $60 million, which will represent the eighth
          sequential quarter of revenue growth, and will represent between 26
          and 35 percent year-over-year revenue growth.

For the first quarter of 2007, the Company reported total revenues of $55.6
million, representing a 55 percent increase as compared to $35.9 million
reported in the first quarter of 2006. Net Loss in accordance with generally
accepted accounting principles (GAAP) for the first quarter of 2007 was $37.4
million, or $0.36 per share, as compared to a GAAP net loss of $45.1 million, or
$0.63 per share, for the first quarter of 2006. Non-GAAP operating profit (as
described and reconciled below) for the first quarter of 2007 was $11.8 million,
as compared to non-GAAP operating profit for the first quarter of 2006 of $5.2
million.

"We take satisfaction that in Q1, which saw a world-wide foundry revenue drop
exceeding ten percent, we achieved the upper range of an aggressive guidance and
are able to guide Q2 to be our eighth consecutive quarter of revenue growth",
said Russell Ellwanger, chief executive officer of Tower Semiconductor. "Driven
by strong customer demand both Fabs ran at above 90 percent utilization rates
during the quarter. As we near the completion of our 50 percent Fab2 capacity
expansion, we believe we are well positioned to continue growth in the second
half of 2007, fueled by multiyear contracts from new and existing customers.
This quarter's results reaffirm our confidence in our business model and
demonstrate the benefits of serving a customer base representing multiple
segments and specialty products in order to enable growth despite the industry
cycles".

BUSINESS OUTLOOK:

Tower expects continued growth in the second quarter of 2007 and forecasts
revenue to be between $56 and $60 million, which will represent between 26 and
35 percent year-over-year revenue growth.

flows provided by operating, investing and financing activities, or other income
or cash flow statement data prepared in accordance with GAAP.

This release, including the financial tables below, presents other financial
information that may be considered "non-GAAP financial measures" under
Regulation G and related reporting requirements promulgated by the Securities
and Exchange Commission as they apply to our company. These non-GAAP financial
measures exclude (1) depreciation and amortization expenses and (2) compensation
expenses in respect of options granted to directors, officers and employees.
Non-GAAP financial measures should be evaluated in conjunction with, and are not
a substitute for, GAAP financial measures. The tables also present the GAAP
financial measures which are most comparable to the non-GAAP financial measures,
as well a reconciliation between the non-GAAP financial measures and the most
comparable GAAP financial measures. The non-GAAP financial information presented
herein should not be considered in isolation from or as a substitute for
operating income, net income or loss, cash flows provided by operating,
