Light emitting diode (led) dies and devices with common anode

A light emitting diode (LED) die comprising:

• a plurality of pixels each having a sidewall and a top surface, and being defined by a mesa of semiconductor layers, each of the mesas including an n-type layer, an active region, and a p-type layer;
• a current spreading layer on the p-type layer of each of the pixels;
• a plurality of junction spacers comprising a spacer dielectric material conformal to the sidewall of each of the pixels;
• a first dielectric material on a portion of the current spreading layer of each of the pixels;
• a plurality of e-vias defined by e-via sidewalls of the first dielectric material, a guard layer on the first dielectric material and disposed in each of the e-vias in contact with the current spreading layer;
• a second dielectric material disposed on a portion of the guard layer of each of the pixels, insulating the n-type layers and the p-type layers of each of the pixels;
• a plurality of p-vias defined by p-via sidewalls of the second dielectric material, a p-metal material plug disposed in each of the p-vias in contact with the guard layer;
• a plurality of n-vias each defined by an n-via spacer sidewall of the spacer dielectric material that extend from a depth of the n-type layer of each of the pixels to an n-metal layer, an n-contact material disposed in each of the n-vias in contact with the n-type layer of each of the pixels;
• for each pixel, the n-metal layer being disposed on surfaces of the n-contact material, the n-via spacer sidewalls, and the second dielectric material, and in contact with a cathode;
• a plurality of p-contact materials disposed in trenches between the mesas;
• for each pixel, a p-metal layer being disposed on the p-metal material plug, the second dielectric material, the junction spacers, and the p-contact materials;
• a passivation layer comprising a passivation dielectric material disposed on the p-metal layer and optionally a portion of the n-metal layer of each of the pixels, and a portion of the second dielectric material, insulating the cathode of each of the pixels and the p-contact materials;
• and
• a common anode in communication with each of the p-contact materials.
