Abstract
Described are light emitting diode (LED) devices comprising a plurality of mesas defining pixels, each of the mesas comprising semiconductor layers, an N-contact material in a space between each of the plurality of mesas, a dielectric material which insulates sidewalls of the P-type layer and the active region from the metal. A multilayer composite film is on the P-type layer, the multilayer composite film comprising: a current spreading layer on the P-type layer, the current spreading layer having a first portion and a second portion; a dielectric layer on the second portion of the current spreading layer; a via opening defined by sidewalls in the dielectric layer and the first portion of the current spreading layer; and a P-contact layer in the via opening on the first portion of the current spreading layer, the sidewalls in the dielectric layer, and on at least a portion of the dielectric layer.
