Interestingly, DUV lithography at a wavelength of 193 nm has dominated the field much longer than originally expected, with a continual series of improvements prolonging its lifespan. The ...
EUV is state-of-the-art, but larger-wavelength DUV and FUV are more than adequate for the billions of microcontrollers made every year. There are myriad applications for chips that do not require ...
