CO2 Lasers Create Integrated Circuits for Mobile Phones
Did you know that CO2 lasers are used to create cutting-edge integrated circuits in your mobile phones? Extreme ultraviolet lithography (EUVL) systems use a 30-kW, short pulse CO2 laser focused on a 30 µm liquid tin droplet, repeatedly 50,000 times per second, to produce 250 W of EUV light at a 13.5 nm wavelength. The … Continue reading
