Led packages having improved light extraction |
摘要 |
A light-emitting microelectronic package includes a light-emitting diode (110) having a first region (114) of a first conductivity type, a second region (116) of a second conductivity type, and a light-emitting p-n junction (118) between the first and second regions. The light-emitting diode defines a lower contact surface (120) and a mesa (122) projecting upwardly from the lower contact surface. The first region (114) of a first conductivity type is disposed in the mesa (122) and defines a top surface of the mesa, and the second region (116) of a second conductivity type defines the lower contact surface that substantially surrounds the mesa (122). The mesa includes at least one sidewall (130) extending between the top surface (124) of the mesa and the lower contact surface (120), the at least one sidewall (130) having a roughened surface for optimizing light extraction from the package.
