ASML ships AT:1100 ArF imaging system

Press release - Veldhoven, the Netherlands, December 21, 2001

ASML today announced the first shipment of its dual-stage ArF (193 nm) lithography system for 300 mm wafer processing. The system was shipped this month to a leading global semiconductor manufacturer.

Introduced in July 2001, the AT:1100 system builds upon ASML's successful 300 mm TWINSCAN dual-stage platform and was developed as the industry's first high-productivity ArF lithography system for volume production applications of 300 mm wafers at the 100 nm technology node.

Doug Dunn, ASML's president and CEO, said: "This TWINSCAN AT:1100 shipment means we are first to market with leading-edge 0.10 micron ArF imaging technology. It marks ASML's commitment to delivering new product to customers well ahead of our competitors."

The AT:1100 incorporates a Carl Zeiss ArF StarLith 1100 lens, which features the highest numerical aperture (0.75) available in an ArF lens. The StarLith's improved aberration control reduces influence on critical lithography structures, which enhances the imaging performance. The AT:1100 is designed for seamless mix-and-match operation with ASML's TWINSCAN product family, including the AT:850, a 248 nm deep UV system, and the AT:400, an i-line system, thereby ensuring the lowest cost per level even with advanced process technologies. The TWINSCAN platform allows either left- or right-hand configuration for optimum fab layout with track processing equipment and 300 mm automated materials handling systems. The modular design reduces system installation time for faster fab ramp up and time to market for advanced chips.
