- Detail
- Parameters
Such product is the basement for subsequent UVC-LED device fabrication. After treated by series of tape-out processes, e. g.
photolithography, electrode deposition et al., the UVC-LED is fabricated, and it presents excellent sterilization performance to
various microorganism, including Coronavirus-19. Currently we have successfully achieved 2 inch UVC-LED epilayer with uniform
265 nm irradiation wavelength.
