Flip chip light emitting diode with micromesas and a conductive mesh

A flip chip light emitting diode including:

• a light-transmissive substrate;
• a base semiconducting layer of a first conductivity type disposed on the light-transmissive substrate;
• light-emitting micromesas disposed on the base semiconducting layer;
• a first conductivity type electrode disposed on the base semiconducting layer, the first conductivity type electrode including a bonding pad region and at least one conductive finger extending from the bonding pad region to effect electrical communication between the first conductivity type electrode and the light-emitting micromesas;
• an insulating layer disposed over the base semiconducting layer and the at least one conductive finger of the first conductivity type electrode, the insulating layer having openings to expose the bonding pad region of the first conductivity type electrode and topmost portions of the micromesas;
• and
• a second conductivity type electrode layer disposed over the insulating layer and the light-emitting micromesas, the insulating layer insulating the second conductivity type electrode layer from the at least one conductive finger of the first conductivity type electrode and the base semiconducting layer.

A flip chip light emitting diode including:

• a light transmissive substrate;
• a base semiconducting layer disposed on the light transmissive substrate;
• light emissive micromesas arranged on the base semiconducting layer, the light emissive micromesas defining an active area of the light emitting diode;
• a continuous electrode layer disposed over the active area and contacting the tops of the micromesas, the continuous electrode layer being substantially co-extensive with the active area of the light emitting diode;
• an electrically conductive mesh deposited on the base semiconducting layer in trenches between the micromesas, the electrically conductive mesh defining a continuous electrode that is substantially co-extensive with the active area of the light emitting diode;
• and
• a discrete electrode disposed outside of the active area of the light emitting diode, the discrete electrode electrically communicating with the conductive mesh.
