High Brightness LED (“HB-LED”) usage is increasing for new applications as manufacturing costs decrease and performance improves. HB-LED applications such as mobile phone LCD screens and keypads and flashlights for camera phones have been the drivers for HB-LED manufacturing market growth in the last couple of years, as well as car headlights, LCD TV backlights and traffic signaling. HB-LED’s typically are used for high-end applications, making quality control imperative. Our ICOS LED wafer inspection system offers outgoing automated visual inspection of HB-LED wafer manufacturing for quality of the wafer surface.
