The industry’s most productive lithography platform yet is the first to go beyond 300 wafers per hour.

Key features & benefits
The TWINSCAN NXT:1470 193 nm step-and-scan system is the first ever “dry” lithography system built on our high-productivity, high-precision NXT platform. As a result, it is the first dry system to achieve on-product overlay better than 4.5 nm – and the first lithography machine of any kind capable of processing more than 300 wafers per hour.
With its outstanding overlay and throughput performance, this dual-stage ArF lithography tool helps chip manufacturers reduce cost per exposure while producing up to 50% more wafers from the same lithocell footprint. It will enable the planned KrF NXT systems to further reduce the cost of chip production while improving matched-machine overlay for higher yields.
With its NXT body – featuring a new generation of wafer stage module – the NXT:1470 delivers up to 50% greater throughput than our previous fastest ArF system. It is supported by an ongoing roadmap to increase productivity even further, helping manufacturers continue to improve the cost effectiveness of high-volume chip production.
The TWINSCAN NXT:1470 features a variable-NA (0.70 – 0.93) Carl Zeiss Starlith 4X reduction lens. Compared to our previous dry ArF lithography systems, it includes an additional lens element and enhanced improvements for lens heating control.

The TWINSCAN NXT:1470 is built on the latest version of our NXT high-throughput, high-precision system architecture, featuring improved wafer stages and wafer handlers. Combined with the enhanced optics and improved lens and reticle heating control, it enables on-product overlay below 4.5 nm – while processing over 300 wafers per hour.
With polarized illumination, the NXT:1470 can reach production resolutions down to 57 nm. In addition, latest UV level sensor ensures superior focus control over the full wafer, especially for edge dies.
