A research team at Seoul National University (SNU) successfully grew a Micro LED array on a 100 nm-thick sapphire nano-membrane. The results were published on Scientific Reports on May 5, 2020. According to the published paper, the team, led by Euijoon Yoon of the Department of Materials Science and Engineering of SNU, designed the sapphire nano-membrane array to grow an array of multi-faced Micro LEDs sized 4 μm × 16 μm. With the method, the Micro LED chip singulation does not need to go through plasma etching process, leading to a better ext...
