FSI International´s 2008 Knowledge Services(TM) Seminar Series Offers Attendees Insight into Surface Preparation Drivers and Processes for Advanced Technology Generations

FSI International, Inc. (Nasdaq: FSII) announces today the return
of its successful Knowledge Services(TM) Seminar Series in Tel Aviv,
Dresden, Grenoble, and adds Milan to the May 2008 series schedule. The
full-day seminars will focus on surface conditioning challenges and
solutions, and will feature technical presentations from FSI, major
semiconductor manufacturers and research facilities, including ST
Microelectronics, Intel, Qimonda and CEA/Leti. Dr. Srini Raghavan,
professor of Materials Science and Engineering, University of Arizona,
will present a short course on "Cleaning Chemistry Compatibility with
New IC Device Materials."

"Dr. Raghavan is a well-known expert in the field of applied
surface chemistry," said Don Mitchell, FSI chairman and CEO. "Dr.
Raghavan has lectured on a variety of cleaning topics at FSI´s
Knowledge Services Seminars around the world, and we are pleased that
he is able to participate again this year." He added, "Our customers
find the Knowledge Services Seminar Series to be of great value--they
can collaborate with other industry veterans and learn about specific
technology challenges and cleaning solutions. By combining Dr.
Raghavan´s short course with customer presentations, the seminars
deliver well-rounded coverage of both the theoretical and practical
aspects of today´s most advanced manufacturing processes."

Seminars have attracted more than 1,500 IC manufacturing engineers and
managers across Asia, Europe, Israel and the United States. The short
course is presented in the morning, followed by a technical session.
The technical session topics will include: cleaning challenges for
phase change memory, cleaning challenges for DRAM, drivers for low
silicon loss during cleaning, ashless photoresist stripping, salicide
formation, single wafer cleaning technology, Cu/Low-k post etch/ash
cleaning, cryogenic aerosol, batch immersion, wafer reclaim, among
other important subjects.
