摘要：

A surface texturing scheme using ablation etching by KrF excimer laser irradiation and chemical wet etching is demonstrated to improve the light-extraction efficiency of GaN-based thin-film flip-chip light-emitting diodes (TFFC-LED). Both simulated and experimental results on the light emission characteristics are presented and discussed. For the TFFC-LED (die size of 1x1 mm(2)) with the proposed surface roughening scheme, enhancements in light output power (LOP) by 13.08% (12.81%) and wall-plug efficiency (WPE) by 2.87% (2.25%) at 350 mA (700 mA) as compared with that of the TFFC-LED without surface texturing are achieved experimentally.
