FSI International Receives Repeat ORION® System Order

MINNEAPOLIS--(BUSINESS WIRE)--FSI International, Inc. (Nasdaq: FSII), a leading manufacturer of surface conditioning equipment for microelectronics manufacturing, announced today that it received a repeat ORION^® single wafer cleaning system order from a leading foundry producer. The order is expected to ship in the fourth quarter of fiscal 2011.

The customer will use the system for back-end-of-line (BEOL) cleaning processes. Foundry and logic manufacturers are finding low-k materials and metal film stacks used for advanced devices are much more sensitive to wet cleaning than previous generations of BEOL processes. The closed chamber technology of the ORION^® system has demonstrated highly efficient removal of etch and ash by-products without causing galvanic corrosion or changes in metal and dielectric film properties.

Using the company’s broad portfolio of cleaning products, which include batch and single-wafer platforms for immersion, spray, vapor and cryogenic aerosol technologies, customers are able to achieve their process performance flexibility and productivity goals.
