    Engineers develop first deep-UV microLED display chip for maskless photolithography

    Electroluminescence (EL) images show that devices of various sizes operate effectively at operating current densities, even the smallest 3 μm devices. UVC microdisplays provide excellent uniformity and significant light output, allowing successful implementation of pattern transfer processes.
