Just as the first lights of a new millennium were dawning in 1999, ASML announced its newest lithography product, The TwinScan Scanning Stepper. Here was a tool representing the latest in technology: a bridge tool spanning the 200/300 mm wafer size; a lens family capable of ranging from i line at 365 nm down to ArF lenses compatible with 193 nm; variable focal depth adjustment; improved overlay down to 0.6nm; and symmetrical side loading for foups.

These are just a few of the advancements that helped propel ASML to the leading supplier of steppers in the late twentieth and early twenty-first centuries.
