Abstract

A micro-LED device and a method of fabricating the micro-LED device are disclosed. The method includes processing from a first side (e.g., p-side) of epitaxial layers of a micro-LED wafer to form individual mesa structures and a first solid metal bonding layer on the mesa structures, bonding a second solid metal bonding layer on a backplane wafer to the first solid metal bonding layer of the micro-LED wafer, removing the substrate of the micro-LED wafer and processing from a second side (e.g., n-side) of the epitaxial layers to isolate the solid metal bonding layers and form individual electrodes (e.g., anodes) for individual micro-LEDs, forming a dielectric material layer on surfaces in regions between the mesa structures, and depositing one or more metal materials in the regions between the mesa structures to form mesa sidewall reflectors and a common electrode for the micro-LEDs.
