ASM Wins New Taiwanese Customer for 300mm Vertical Furnace

Order Exceeds US$30 Million

BILTHOVEN, The Netherlands, February 26, 2007 - ASM International N.V. (Nasdaq: ASMI and Euronext Amsterdam: ASM) today announced that its subsidiary, ASM Europe B.V., has recently received an order from a major memory chip manufacturer in Taiwan for multiple A412™ 300mm Vertical Furnaces. Delivery of the systems order, valued at over US$30 million, will commence in May 2007. This order is subsequent to another ASM vertical furnace win in Taiwan reported earlier this quarter, which also totaled more than US$30 million.

“We are especially pleased with this new customer’s business,” said Dr. Tanja Claasen, ASM’s Vertical Furnace Product Manager. “It indicates the level of confidence we are being granted in the memory market today. And it represents another big step forward for our vertical furnace product line, further expanding our presence in Taiwan.”

“With two reactors and four process boats per system, ASM’s furnaces are designed for optimum productivity and low cost of ownership - two factors that are valued highly in Taiwanese business,” added Dr. Claasen.

According to the U.S. Taiwan Business Council, Taiwan is expected to become the world’s largest DRAM producer in 2007, leading the industry in semiconductor fab equipment spending.
