The failure analysis of LED sulfur corrosion
As a common problem of LED failure,the sulfur corrosion that can cause the LED luminous flux reduced,LED color temperature drifted,in the most severe cases,LED damaged.The sulfur corrosion of LED which affected the reliability of LED was always the focus of research.In this paper,the general analysis methods about the LED sulfur corrosion were clearly elaborated.The SEM&EDS,TOF-SIMS and AES were applied,which provided new methods to analysis the sulfur corrosion.Meanwhile,the corrosion path was discussed.Then,how to avoiding the sulfur corrosion of LED was also suggested.
