        Ibis Technology Announces Second Quarter 2005 Results;
           Charles M. McKenna Named Chief Operating Officer

    DANVERS, Mass.--(BUSINESS WIRE)--July 20, 2005--Ibis Technology
Corporation (Nasdaq NM: IBIS), a leading provider of SIMOX-SOI
implantation equipment to the worldwide semiconductor industry, today
announced its financial results for the second quarter ended June 30,
2005.
    Due to the fact that the company discontinued its wafer
manufacturing business, as reported in July 2004, the recording of
wafer sales in this quarter and wafer revenue in previous quarters are
now being reported net of related costs as gain or loss from
discontinued operations in the company's statements of operations.
Financial information for this quarter and previously reported
quarterly and year to date information has been so adjusted for
comparative purposes.
    Total revenues for the second quarter of 2005 were $198,000,
compared to $167,000 in the preceding quarter, and compared to total
revenues of $203,000 in the second quarter of 2004.
    Net loss for the 2005 second quarter was $2.6 million, or $0.25
per share, including a loss of $57,000 from discontinued operations.
Excluding the loss from discontinued operations, the second quarter
net loss was $2.6 million, or $0.24 per share. Net loss for the
preceding quarter was $2.7 million, or $0.25 per share, including a
gain from discontinued operations of $42,000. Net loss in the second
quarter of 2004 was $3.4 million, or $0.32 per share, including a loss
from discontinued operations of $1.3 million, or $0.13 per share. Net
loss in the second quarter of 2004 excluding the loss from
discontinued operations was $2.1 million, or $0.19 per share.
    For the first half of 2005, total revenues were $365,000 compared
to $411,000 for the first half of last year. Net loss for the first
six months of 2005 was $5.3 million, or $0.50 per share, including a
loss from discontinued operations of $15,000. For the same period last
year net loss was $6.8 million, or $0.64 per share, including a loss
from discontinued operations of $2.7 million, or $0.25 per share.
    In a separate press release issued by Ibis today, the company
announced that Charles M. McKenna has been named executive vice
president and chief operating officer, effective today. McKenna will
report directly to Martin J. Reid, Ibis' president and CEO, and will
be responsible for managing the company's worldwide engineering,
production and sales and marketing operations, plus a range of support
functions.
    "We are very pleased to have Chuck McKenna join Ibis in this
important, senior management role," said Reid. "Chuck has a wide
variety of executive management skills, and the timing of his joining
the company couldn't be better. We believe that our customers are
seeing increasing interest in SIMOX-SOI wafers, and we are at a point
where potential implanter demand requires the kind of strategic
planning and management expertise Chuck has demonstrated so well in
the past. His vast network of key contacts in this industry, combined
with his skill in managing rapid, cost-effective growth will serve us
well."
    Commenting on the results of the second quarter, Reid said, "In
mid-June, we announced the shipment of an Ibis i2000 oxygen implanter
to Sumitomo Mitsubishi Silicon Corporation (SUMCO). The implanter had
completed the factory acceptance process, and was scheduled for
installation at SUMCO's plant in Japan. The implanter now has been
installed and is undergoing final adjustments before initiating
on-site acceptance testing." The company continues to expect to
recognize revenue on the sale of this implanter by the end of this
year.
    This is the third i2000 implanter that has been sold by Ibis, and
the second to a leading silicon wafer manufacturer. "As we have said
before," said Reid, "we believe that the silicon wafer manufacturers
are the ones who will be able to leverage the cost efficiencies of the
SIMOX process and deliver quality, economical SOI wafers to the
world's chipmakers. We continue to emphasize our strategic partnership
with the wafer suppliers, working very closely with them to improve
implanter throughput and product quality."
    "It was one year ago that we announced the discontinuance of the
wafer-manufacturing portion of our business," said Reid. "This was
done so we could focus our energies and resources on our equipment
business. Since the time of that announcement, we have made great
strides in developing, expanding and reinforcing our relationships
with the world's silicon wafer suppliers. The strength of these
partnerships, combined with the technological advancements that have
been made through joint development activities with our wafer supplier
customers, has demonstrated that we are on the right path."

    Corporate Outlook

    Commenting on the company's future outlook, Reid said, "Based on
meeting certain customer engineering requirements, we expect final
customer acceptance of the SUMCO implanter by year end. In addition,
we expect to receive another implanter order by the end of this year,
based on achieving planned improvements in implanter performance. We
also look forward to positive prospects for orders in 2006, once our
technology improvement goals have been met. However, the SOI market is
still in its early stages and the pace of SOI adoption is difficult to
predict; therefore, forecasting implanter sales is extraordinarily
difficult and there are no guarantees that these orders will be
forthcoming."
    The company ended the second quarter of 2005 with approximately
$8.0 million in cash and believes it will have sufficient cash on
hand, including cash expected to be received upon final customer
acceptance of the SUMCO implanter shipped in June 2005, to support
operations at current levels through at least the first quarter of
2006. Revenue recognition and receipt of the final 20 percent of the
purchase price based on final customer acceptance at the customer's
facility in Japan is expected by the end of this year. These
expectations are based on current operating plans and the company's
general sales outlook, each of which may change rapidly. The company
intends to continue to invest in research, development and
manufacturing capabilities. Changes in technology or sales growth
beyond currently established capabilities may require further
investment.
