Abstract
A light emitting diode (LED) structure has semiconductor layers, including a p-type layer, an active layer, and an n-Type layer. The p-type layer has a bottom surface, and the n-type layer has a top surface though which light is emitted. A copper layer has a first portion electrically connected to and opposing the bottom surface of the p-type layer. A dielectric wall extends through the copper layer to isolate a second portion of the copper layer from the first portion. A metal shunt electrically connects the second portion of the copper layer to the top surface of the n-type layer. P-metal electrodes electrically connect to the first portion, and n-metal electrodes electrically connect to the second portion, wherein the LED structure forms a flip chip. Other embodiments of the methods and structures are also described.
