Light Emitting Devices (LEDs) are fabricated on a wafer substrate with one or more thick metal layers that provide structural support to each LED. The streets, or lanes, between individual LEDs do not include this metal, and the wafer can be easily sliced/diced into singulated self-supporting LEDs. Because these devices are self-supporting, a separate support submount is not required. Before singulation, further processes may be applied at the wafer-level; after singulation, these self-supporting LEDs may be picked and placed upon an intermediate substrate for further processing as required. In an embodiment of this invention, protective optical domes are formed over the light emitting devices at the wafer-level or while the light emitting devices are situated on the intermediate substrate.

A light-emitting device includes a substrate; a light-emitting element mounted on the substrate; a first light-transmissive member bonded to an upper surface of the light-emitting element via an adhesive; and a second light-transmissive member placed on an upper surface of the first light-transmissive member. In a plan view of the light-emitting device, a peripheral edge of a lower surface of the first light-transmissive member is positioned more inward than a peripheral edge of the upper surface of the light-emitting element. The adhesive extends from the upper surface of the light-emitting element to a lower surface of the second light-transmissive member, the adhesive covers a side surface of the first light-transmissive member, and the adhesive is separated from the substrate.

A light emitting device includes a base member, a light emitting element, a wire, a protective film, first and second resin members, and a light shielding portion. The base member has a conductive member. The wire connects the light emitting element and the conductive member. The protective film covers the conductive member to be spaced apart from a portion of a connecting portion. The first resin member has a first gas barrier property with respect to hydrogen sulfide and a first light resistance. The second resin member has a second gas barrier property with respect to hydrogen sulfide lower than the first gas barrier property and a second light resistance higher than the first light resistance. The light shielding portion is disposed on a surface of the base member and disposed on a line connecting the light emitting element and the first resin member.
