The company claims its technology can create chip features 10 times smaller than current lithography systems, with a beam width of just 0.1 nanometers compared to the 13.5nm wavelength used by ASML's EUV scanners. Lace aims to have a test tool running in a pilot fab by 2029. The advantage of Lace’s system is that atoms don’t have a diffraction limit, whereas photon-based lithography, including ASML's EUV systems, is constrained by the wavelength of the light it uses.…
