a base portion located between the lens portion and the supporting member in the first direction and surrounding the light-emitting element,
wherein a distance between the element back surface and the base back surface in the first direction is larger than a dimension of the base portion in the first direction.

SUB PIXEL LIGHT EMITTING DIODES FOR DIRECT VIEW DISPLAY AND METHODS OF MAKING THE SAME

GLO AB, Lund (SE)


1. A method of forming a light emitting diode (LED), comprising: forming a n-doped semiconductor material layer over a substrate; forming an active region including an optically active compound semiconductor layer stack configured to emit light on the n-doped semiconductor material layer; forming a p-doped semiconductor material layer on the active region; depositing a nickel layer directly on the p-doped semiconductor material layer; etching back the nickel layer to expose a nickel-doped surface region of the p-doped semiconductor layer; and forming a conductive layer on the exposed nickel-doped surface region.

METHODS FOR GROWING LIGHT EMITTING DEVICES UNDER ULTRA-VIOLET ILLUMINATION

LUMILEDS LLC, San Jose, ...


1. A method for forming a light emitting diode (LED), the method comprising:epitaxially growing a III-nitride n-type layer over a growth substrate;
epitaxially growing an active layer over the III-nitride n-type layer;
epitaxially growing a III-nitride p-type layer over the active layer in the presence of hydrogen and magnesium;
annealing at least the III-nitride p-type layer in situ to activate magnesium dopants in the III-nitride p-type layer;
ceasing the anneal;
epitaxially forming a first portion of a III-nitride tunnel junction n-type layer over the III-nitride p-type layer to form a tunnel junction light emitting diode;
illuminating a surface of the first portion of the III-nitride tunnel junction n-type layer with light having a photon energy higher than the III-nitride p-type layer's band gap energy during growth; and
epitaxially forming a remainder of the III-nitride tunnel junction n-type layer absent light illumination during growth.
