ASM International N.V. Completes Acquisition of NuTool, Inc.

Bilthoven, the Netherlands, and Milpitas, California, June 3, 2004 - ASM International N.V. (NASDAQ: ASMI and Euronext Amsterdam: ASM) said today that it has completed the acquisition of NuTool, Inc., a privately-held semiconductor equipment company located in Milpitas, California. 
As indicated in the March 2, 2004 announcement of its agreement to acquire NuTool, ASMI has purchased the 85% of NuTool not already owned by ASMI, in exchange for ASMI common stock.  The number of ASMI shares issued at closing was 1,962,282 or 3.9 % of the currently outstanding shares.  In addition, ASMI issued replacement employee stock options to NuTool employees to purchase an aggregate of 57,720 shares of ASMI common stock and ASMI may issue up to an additional 806,375 shares, or 1.6 % of its currently outstanding shares over the next three years based on NuTool's achievement of various performance targets.
Arthur del Prado, president and CEO of ASM International commented, "With the completion of ASMI's acquisition of NuTool today, we at ASMI are delighted to have solidified this vital strategic initiative that we believe will have far reaching benefits for both ASMI and NuTool, as it raises our company's competitive standing in back-end of line (BEOL).  With its breakthrough electrochemical mechanical deposition, or ECMD‘ technologies, NuTool brings our company a unique capability that complements ASMI's suite of metals and dielectric film deposition technologies, which includes our patented Aurora“ low-k film, and provides ASMI with the planar copper deposition and removal technology required for integration of ultra and extreme low-k films. Having collaborated with our associates at NuTool for the past two years on the integration of our technologies, we are confident that this amplification of our BEOL roadmap will accelerate adoption of our overall interconnect offering."
            Homayoun Talieh, President of NuTool, added,  "I know I speak for all of us at NuTool in saying how excited we are about the combined potential of ASMI and NuTool, and what the combined companies can offer our industry and its investors.  We believe that NuTool has a fundamentally different technology than that which is currently available in the market. We received confirmation of our technology from the marketplace with the acceptance this year of our first 300mm Lumina Copper ECMDTM platform by a key customer in Europe. As part of ASMI, we now have the critical mass that we believe will allow us to significantly increase customer penetration and to accelerate the development of our products."
