Publication number: 20060124939Abstract: A simplified manufacturing process for massive production of LEDs that have superior light emitting efficiency and superior heat discharging efficiency. The method employs a laser lift-off technique instead of the flip-chip bonding technique and it does not require a photolithography process, thereby substantially reducing the process steps and enhancing the heat discharging efficiency. The LED chips are formed as unit chips before irradiating the laser, thereby increasing the yield and realizing the mass production by preventing cleavage of the crystal structures. Heat discharging efficiency is also increased by roughening the surface of an n-type GaN layer. The light emitting area can be widened 30% more than in the flip-chip technique. Thus, the present invention serves to increase the light output and the heat discharging area, thereby drastically enhancing the performance of manufacturing high-output LEDs.Type: ApplicationFiled: July 7, 2005Publication date: June 15, 2006Inventors: Jae Lee, Bu Shin, Min Choi, Jong Kang, Min Yu, Byung Oh
