Abstract
A method is provided for fabricating an encapsulated emissive element. Beginning with a growth substrate, a plurality of emissive elements is formed. The growth substrate top surface is conformally coated with an encapsulation material. The encapsulation material may be photoresist, a polymer, a light reflective material, or a light absorbing material. The encapsulant is patterned to form fluidic assembly keys having a profile differing from the emissive element profiles. In one aspect, prior to separating the emissive elements from the handling substrate, a fluidic assembly keel or post is formed on each emissive element bottom surface. In one variation, the emissive elements have a horizontal profile. The fluidic assembly key has horizontal profile differing from the emissive element horizontal profile useful in selectively depositing different types of emissive elements during fluidic assembly. In another aspect, the emissive elements and fluidic assembly keys have differing vertical profiles useful in preventing detrapment.
