Abstract

See full text

A method for manufacturing micro-LED displays includes depositing a first material over a substrate having a plurality of micro-LEDs such that the plurality of micro-LEDs are covered by the first material and the first material fills gaps laterally separating the micro-LEDs, removing a portion of the first material from the gaps that laterally separate the plurality of micro-LEDs to form trenches that extend to or below light-emitting layers of the micro-LEDs, depositing a second material over the substrate such that the second material covers the first material and extends into the trenches, and removing a portion of the first and second material over the plurality of micro-LEDs to expose top surfaces of the plurality of micro-LEDs and such that isolation walls positioned in the gaps between the plurality of micro-LEDs extend vertically higher than the top surface of the first material.
