December 6, 2005, Tokyo, Japan--At Semicon Japan, ASML Holding NV (ASML) announced that it has made significant progress toward the development of both high-numerical aperture (NA) immersion and extreme-ultraviolet (EUV) lithography technology--two critical elements in the semiconductor industry's drive to continue its historical trend of packing more power onto silicon chips.

ASML presented the first resist images produced by its Twinscan XT:1700i, a 193-nm immersion scanner aimed at the 45-nm node. The results are made possible by the combination of a 1.2-NA catadioptric lens, polarized illumination, and water-based immersion technology. The lens is performing well within specification and is now ramping up for production. Qualification of the total system is ongoing and the first tool will be ready for shipment by the end of Q1 2006. ASML expects to ship between 20 and 25 immersion systems in 2006, including shipments to Japan.

In addition, ASML described significant progress on its EUV alpha tool development: collaborating vendors of mask blanks (SCHOTT Lithotec), photomasks (Toppan Photomasks), and optical systems (Carl Zeiss SMT) have been shipping their respective components to ASML. While the assembly of two alpha tools is in progress, the first projection system is being qualified and integrated, an important proof-of-concept for EUV lithography. ASML plans to ship the world's first 0.25-NA EUV alpha tools in the second quarter of 2006 to the Interuniversity MicroElectronics Center (IMEC) in Leuven, Belgium, and Albany NanoTech at the State University of New York at Albany, N.Y.

"The progress achieved in high NA immersion and EUV is compelling because both technologies offer real options for 32-nm lithography and beyond. Also, double exposure/double patterning should be considered to possibly extend 193-nm lithography," said Martin van den Brink, ASML's Executive Vice President, Marketing and Technology. "The industry must make roadmap choices and ASML is committed to align to the roadmap of its key customers. As always, we will provide access to early tools for collaborators, vendors and customers. Hands-on experience fosters industry-wide collaboration and will clarify roadmap choices."
