A SOLID STATE LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING A SOLID STATE LIGHT EMITTING DEVICE
Abstract:
A solid state light emitting device includes a light emitting stack (20), a metallization (30), comprising a guard layer (36) of metal, and a dielectric layer (50) over the guard layer (36) of the metallization. During subsequent processing delamination and/or cracking may occur at the edges of the devices, sometimes referred to as die edge defects. To address these defects a plurality of stress-relief elements (62, 64) and/or anchor elements may be provided in an edge region of the metallization and/or dielectric layer for reducing delamination. The stress-relief elements (62, 64) are formed by regions of reduced thickness or increased thickness in the guard layer (36).
