ASML Speeds Production of More Sophisticated Chips

New Tool Shrinks Printing on Chips to 80 Nanometers


VELDHOVEN, The Netherlands, November 20, 2002 - ASML Holding NV (ASML)
today announced a new system that enables semiconductor manufacturers to
achieve greater yield of more sophisticated chips. Called the TWINSCAN(tm)
AT:1200B(tm) Step & Scan System, this new addition to ASML's product line
is slated for delivery in mid-2003. It provides the following benefits to
customers:

     o    Printing more sophisticated chips due to a reduced resolution of
          80 nanometers. At 80 nanometers, approximately 3,000 features
          would fit along the edge of a salt crystal
     o    Allowing for additional shrink without transferring to new
          wavelengths due to 193 nanometer technology
     o    Processing multiple wafers simultaneously due to the TWINSCAN
          dual-stage system
     o    Increasing productivity due to printing more chips per wafer,
          especially with the use of 300-millimeter wafers

Industry estimates indicate that 15 300-millimeter fabs will be operational
worldwide by the end of this year. The number may reach 40 by the end of
2007, with a combined capacity of 800,000 wafers per month.

"Chipmakers may invest as much as US$ 2.5 billion in a fab that operates on
300-millimeter technology. The return on investment needs to be achieved as
quickly as possible," said Doug Dunn, president and CEO, ASML. "This new
lithography system reads like a case study for business success: more
sophisticated chip design plus higher volume manufacturing equals greater
potential profitability for ASML customers."
