We have fabricated high brightness blue light emitting diode (LED) with InGaN/GaN multi-quantum well (MQW) which is sandwiched simply between n-GaN and p-GaN. The LED epitaxial structure was grown by a newly designed metal organic chemical vapor deposition (MOCVD) system with RF heater and vertical gas injection type showerhead. The reactor exhibited a good uniformity of temperature and gas velocity. The uniformity of layer thickness and PL wavelength was less 2% and 1.2nm, respectively. The epoxy molded LED lamp showed radiant power of 4mW at a forward current of 20mA. We note that the power is very high considering such a simple LED structure.
