摘要:	Wafer bonding and laser lift-off (LLO) processes were employed to fabricate pattern sapphire thin-GaN light-emitting diodes LEDs (PT-LED). During the LLO process, the required laser energy for PT-LED was much higher than that for flat thin-GaN LED (FT-LED). The yield rate of PT-LED was low, and the leakage current was high. In this study, the laser lift-off mechanisms of PT-LEDs were investigated. (C) The Author(s) 2014. Published by ECS. All rights reserved.
