One of the only manufacturers of immersion lithography systems is a Dutch company that is a component of what stock market index?
Immersion lithography Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is increased by a factor equal to the refractive index of the liquid. Current immersion lithography tools use highly purified water for this liquid, achieving feature sizes below 45 nanometers. ASML, Canon, and Nikon are currently the only manufacturers of immersion lithography systems.
