Abstract
A solid state light emitting device includes a light emitting stack (), a metallization (), comprising a guard layer () of metal, and a dielectric layer () over the guard layer () 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 () 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 () are formed by regions of reduced thickness or increased thickness in the guard layer ().
