Development of etching solution for roughening GaN film (N-face) for blue light-emitting diodes (blue LED)

林純薬工業電子材料部

Lin Jun Pharmaceutical Industry Co., Ltd. has recently started handling a high-performance etching solution that can etch and roughen the surface of GaN films (N-face) in the blue light-emitting diode process. By roughening the surface, the light extraction efficiency is improved, resulting in a higher luminous efficiency. Our company will continue to propose environmentally conscious functional chemicals to many companies to support the improvement of luminous efficiency in blue LEDs. □ For other functions and details, please refer to the materials.
