ASML is one of the world’s leading manufacturers of chip-making equipment. Headquartered in Veldhoven, the Netherlands, ASML employs more than 14,000 people.
The TWINSCAN XT:860M 248-nm Step-and-Scan system is a high-productivity, dual-stage KrF lithography tool designed for volume 300-mm wafer production at and below 110-nm resolution. Combining the imaging power of a variable 0.55–0.80-NA Carl Zeiss Starlith 860+ 4X reduction lens with AERIAL II and the optional QUASAR XL illuminator technology, the XT:860M extends volume proven KrF technology to 110-nm applications.
Highly line-narrowed 40-W KrF lasers with variable frequency control, in combination with the high optical transmission of the optical system, provide a production throughput of 240 300-mm wph with the lowest possible cost of operation.
