Abstract

Various embodiments of light emitting dies and solid state lighting ('SSL') devices with light emitting dies, assemblies, and methods of manufacturing are described herein. In one embodiment, a light emitting die includes an SSL structure configured to emit light in response to an applied electrical voltage, a first electrode carried by the SSL structure, and a second electrode spaced apart from the first electrode of the SSL structure. The first and second electrode are configured to receive the applied electrical voltage. Both the first and second electrodes are accessible from the same side of the SSL structure via wirebonding.

Description

technical field [0001] The present invention relates to light emitting dies, such as light emitting diodes ("LEDs"), and solid state light emitting ("SSL") devices containing light emitting dies with accessible electrodes and methods of fabrication. Background technique [0002] SSL devices can have light emitting die with different electrode configurations. For example, FIG. 1A is a cross-sectional view of a light emitting die 10 with lateral electrodes. As shown in FIG. 1A , a light emitting die 10 includes a substrate 12 carrying an LED structure 11 comprising an N-type gallium nitride (GaN) 14, a GaN / indium gallium nitride (InGaN) multiple quantum well (" MQW")16 and P-type GaN18. The light emitting die 10 also includes a first electrode 20 on the N-type GaN 14 and a second electrode 22 on the P-type GaN 18 . As shown in FIG. 1A , both the first electrode 20 and the second electrode 22 are located on the front side of the LED structure 11 and are easily accessible. ...
