A flip-chip light-emitting diode (LED) includes: a substrate having a patterned surface formed with a protrusion unit including first and second protrusions; a light-emitting epitaxial layer that is disposed on the second protrusions and that includes first and second semiconductor layers and an active layer interposed therebetween; first and second electrodes connected to the first and second semiconductor layers, respectively; and a passivation layer having an epitaxial-covering portion and a substrate-covering portion. The substrate-covering portion of the passivation layer has a top surface with hillocks having a height lower than that of the second protrusions. A high-voltage light-emitting device is also disclosed.

Flip-chip light-emitting diode and high-voltage flip-chip light-emitting device

A light-emitting diode (LED) includes a light-transmissive substrate having a first surface, an epitaxial structure disposed on the first surface, an insulation structure, and first and second electrodes. The epitaxial structure has an upper surface opposite to the first surface, and a side wall interconnecting the upper surface and the first surface. The insulation structure includes a first insulation layer covering the side wall and the upper surface, and a second insulation layer covering a portion of the first surface that is exposed from the epitaxial structure and the first insulation layer. The first insulation layer is formed with first and second holes through which the first and second electrodes are electrically connected to the epitaxial structure. The second insulation layer is formed with an opening. The insulation structure is made of at least one material selected from silicon oxide, silicon nitride, magnesium fluoride, AlO, TiOand TiO.

Light emitting diode

A light-emitting diode (LED) includes a light-transmissive substrate which has a first surface, an epitaxial structure which is disposed on the first surface, a first insulation layer, and a second insulation layer. The epitaxial structure has an upper surface opposite to the first surface, and a side wall interconnecting the upper surface and the first surface. The first insulation layer covers the side wall and the upper surface. The second insulation layer covers a portion of the first surface that is not covered by the epitaxial structure and the first insulation layer, and has a light transmittance greater than that of the first insulation layer. An LED package, an LED module, and a display device including the LEDs are also disclosed.

A light emitting device includes a substrate, a light emitting unit disposed on the substrate, a metallic electrode unit, a metallic adhesion layer disposed on the first and second electrodes of the electrode unit, and a protective layer disposed on the adhesion layer. The first electrode is disposed on a portion of a first-type semiconductor layer of the light emitting unit. The second electrode is disposed on a second-type semiconductor layer of the light emitting unit disposed on a separated portion of the first-type semiconductor layer. The first and second electrodes are partially exposed by the protective layer and the adhesion layer that is partially exposed by the protective layer. A production method for the light emitting device is also disclosed.
