What they do

Problem

Advanced chipmakers lack sufficient access to cutting-edge, high-throughput lithography tools needed to keep shrinking transistors and increase chip performance, especially in Western supply chains.

Solution

It is developing a next-generation lithography machine using a miniaturized particle-accelerator-based high-power light source to increase transistor density and boost throughput.

Who it's for

Semiconductor foundries and advanced chip manufacturers that run high-volume wafer fabrication lines.
