Abstract
Exemplary processing methods include forming a group of LED structures on a substrate layer to form a patterned LED substrate. A light absorption barrier may be deposited on the patterned LED substrate. The methods may further include exposing the patterned LED substrate to light. The light may be absorbed by surfaces of the LED structures that are in contact with the substrate layer, and the light absorption barrier. The methods may still further include separating the LED structures for the substrate layer. The bonding between the LED structures and the substrate layer may be weakened by the absorption of the light by the surfaces of the LED structures in contact with the substrate layer.
