The dielectric layer has a refractive index substantially matching a refractive index of the stack of semiconductor layers. The dielectric layer has a principal surface distal from the stack of semiconductor layers. The distal principal surface includes patterning, roughening, or texturing configured to promote extraction of light generated in the stack of semiconductor layers.

摘要： In a light emitting device, a light emitting chip (12, 112) includes a stack of semiconductor layers (14) and an electrode (24, 141, 142) disposed on the stack of semiconductor layers. A support (10, 10', 110, 210) has a generally planar surface (30) supporting the light emitting chip in a flip-chip fashion. An electrically conductive chip attachment material (40, 41, 141, 142) is recessed into the generally planar surface of the support such that the attachment material does not protrude substantially above the generally planar surface of the support. The attachment material provides electrical communication between the electrode of the light emitting chip and an electrically conductive path (36, 36') of the support. Optionally, at least the stack of semiconductor layers and the electrode of the light emitting chip are also recessed into the generally planar surface of the support.

摘要： A method for separating individual optoelectronic devices, such as LEDs, from a wafer includes directing a laser beam (256) having a width toward a major surface of the semiconductor wafer. The laser beam has an image with a first portion of a first energy per unit width and a second portion of a second energy per unit width less than the first energy. The laser beam image (266) cuts into the first major surface of the semiconductor wafer to produce individual devices.

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.
