Claim Text:
1. A light-emitting device, comprising: a semiconductor epitaxial laminated layer that comprises an N-type semiconductor layer, a P-type semiconductor layer, and a light-emitting layer between the N-type semiconductor layer and the P-type semiconductor layer, wherein the semiconductor epitaxial laminated layer has a surface with deflected dislocations; and an electromigration resistant metal filled into deflected dislocations at the N-type or/and P-type semiconductor layer surface through pretreatment to block an electromigration channel formed over the semiconductor epitaxial laminated layer due to the deflected dislocations to thereby reduce leakage current, wherein the electromigration resistant metal is only located in the deflected dislocations at the semiconductor epitaxial laminated layer surface to optimally reduce light absorption.
