FSI International Introduces FlashClean™ Advantage for Industry-Leading Productivity and Performance

Package provides benefits on the world’s number one batch spray processor

MINNEAPOLIS (July 9, 2003) -- FSI International, Inc. (Nasdaq: FSII) today introduced the new FlashClean™ Advantage package for use on its ZETA® Surface Conditioning Systems. The FlashClean Advantage package consists of hardware, software and process advancements, which further enhance the ZETA System’s productivity and performance. Field upgrades are available for the currently installed base of ZETA Systems.

The ZETA System with FlashClean Advantage provides users with substantial productivity benefits through shortened process time and increased throughput. The cycle time reduction benefits all ZETA System applications. In back-end-of-line (BEOL) post-ash clean, the ZETA System with FlashClean Advantage offers a cycle time that is up to 30 percent shorter than competing batch spray systems, and up to 15 percent faster than competing single wafer wet processors. The system also provides excellent particle performance down to 60-nm, resulting in superior die yield.

“In today’s fiercely competitive environment, IC manufacturers must improve their bottom line. Increasing yield and enhancing productivity in surface conditioning processes, through technology such as our ZETA System with FlashClean Advantage, are two key ways to accomplish this goal,” said Don Mitchell, chairman and CEO of FSI International. “FSI is focused on continuously finding new ways to improve our technology platforms to ensure that we maintain our position as the market share leader in batch spray products.”

FSI’s ZETA Surface Conditioning System includes fully automated configurations for 200-mm and 300-mm wafer sizes and semi-automated configurations for 200-mm and 150-mm wafer sizes. Designed for front-end-of-line (FEOL) and BEOL cleaning processes at technology nodes of 130-nm and below, the ZETA System is proven for a wide range of applications, including FEOL resist strip and post-ash clean, BEOL post-ash clean, salicide strip, C4 cleans and wafer reclaim. The system uses centrifugal spray technology; wafers undergo dry-in, dry-out processing in a closed, nitrogen-purged chamber. FSI's versatile chemical delivery technology prepares the chemicals at controlled composition and temperature and delivers them directly onto the wafers.

FSI International Inc. is a global supplier of surface conditioning equipment technology and support services for microelectronics manufacturing. Using the Company’s broad portfolio of cleaning products, which include batch and single-wafer platforms for immersion, spray vapor and CryoKinetic technologies, customers are able to achieve their process performance, flexibility and productivity goals.

The Company’s support services programs provide product and process enhancements to extend the life of installed FSI equipment enabling worldwide customers to realize a higher return on their capital investment.
