           Ibis Technology Announces Resignation of Jay Blake as Vice
                       President of Equipment Engineering


     DANVERS, Mass.--(BUSINESS WIRE)--Dec. 1, 2005--Ibis Technology Corporation
(Nasdaq NM: IBIS), a leading provider of SIMOX-SOI implantation equipment to the
worldwide semiconductor industry, today announced that Dr. Julian Blake, its
vice president of engineering, will be leaving the Company to pursue other
opportunities. Blake is expected to stay with the Company through early December
and consult with the Company as required for a period of time after his
departure. Charles McKenna, who recently joined Ibis Technology as Chief
Operating Officer, will additionally take over as acting Vice President of
Engineering and assume Blake's responsibilities.
     "We will be sorry to see Jay leave," said Martin J. Reid, president and
chief executive officer of Ibis Technology Corporation. "He was involved with
the early design of the SIMOX equipment at Eaton Corporation before the spin out
of its semiconductor group and has been with Ibis for seven years. We appreciate
his efforts and contributions, and wish him every success in his future
endeavors."
     Blake said, "This was a difficult decision. I enjoyed my time at Ibis, and
I believe that we have developed a process and evolved a second generation tool
in the i2000 implanter that will support the pursuit of Moore's law through the
45-nanometer feature size. As the demand for SOI wafers increases, the SIMOX
cost advantage will play an increasingly important role in Ibis' success. I wish
the best for the whole Ibis team."
     "Building from the foundation that Jay has helped to create, we will
continue our focus on lowering the cost of ownership for the i2000 implanter
through additional gains in wafer quality and throughput while we continue to
explore improvements in SIMOX process technology," said McKenna. "We are also
beginning to focus our attention on improvements in manufacturability with an
eye toward reducing cost and optimizing the modularity of major assemblies."
     Blake joined Ibis as vice president of engineering in March of 1998.
