Abstract

A method for forming a light-emitting-diode (LED) array is disclosed includes forming an LED structure on a substrate. The LED structure is divided into at least a first LED device and a second LED device with a gap between the first LED device and the second LED device. At least one polymer material is deposited over the LED structure to substantially fill the gap with the at least one polymer material. Portions of the at least one polymer material are removed to expose a first electrode of the first LED device and a second electrode of the second LED device. An interconnect is formed on top of the at least one polymer material electrically connecting the first and second electrode.
