Patent ID: 8654810

Claim:
A light-emitting device comprising: a supporting base including a depression section on a top surface thereof, the depression section having an inclined surface on a side wall thereof, the side wall spacing the depression section from an uppermost section of the top surface; a first light-emitting element arranged on a bottom surface of the depression section; a second light-emitting element arranged on the first light-emitting element and the supporting base; a first electrode (i) arranged on the uppermost section of the top surface of the supporting base, and (ii) spacing the second light-emitting element from the uppermost section of the top surface of the supporting base; and a second electrode (i) spacing the first light-emitting element from the depression section of the supporting base, (ii) extending along the inclined surface of the depression section, and (iii) operable to supply electricity to the first light-emitting element, wherein, the first electrode and the second electrode are laterally spaced from each other along the top surface of the supporting base; wherein, the supporting base includes an oxidized film between a first silicon substrate and a second silicon substrate, the depression section is arranged in the second silicon substrate, and the depth of the depression section corresponds to the thickness of the second silicon substrate.
