ASML makes breakthrough in EUV chipmaking tech, plans to increase speed by 50% by 2030 — new 1,000-watt light source fires three lasers at 100,000 tin droplets

Yet, the actual 1000W EUV radiation source will also be equipped with a new tin droplet that will almost double the number of tin droplets to 100,000 every second. This unit is also currently under development, and it will take years before it is commercialized, according to an ASML spokesperson speaking with Tom's Hardware .

Building a new laser system that comprises of a CO2 laser with a 10μm wavelength for the main pulse and two non-CO2 lasers for with ~1μm wavelength for pre-pulses and a new tin droplet generator that doubles performance as well as a new tin droplet generator with twofold performance sounds easy on paper, both these devices as well as devices that accompany them to make their work possible represent numerous major technological breakthroughs.

Increasing the number of tin droplets automatically means increasing the amount of debris that can end up on a wafer (or rather a pellicle), so they must be promptly removed, which means an all-new debris collector. While producing 1000W of EUV radiation is hard, transferring it onto a wafer is even harder, so ASML had to invent all-new high transmission projection optics, which are meant to scale all the way to over 450 wafers per hour, or toward something like 1500W. Also, increased productivity and higher performance light sources require new wafer and reticle stages, which will also be upgraded in systems featuring a 1000W light source. Last but not least, a 1000W EUV light source also calls for new resists and pellicles, so in addition to ASML itself, the whole industry needs to prep for the arrival of the company's tools featuring its latest innovations.

ASML has long planned to increase the productivity of its EUV lithography scanners to 330 wafers per hour by around 2030, a productivity level tied to a 1000W light source. Therefore, the announcement made this week outlines the technology the company invented to achieve that roadmap goal.
