Abstract
A method of manufacturing a micro-light-emitting diode display includes processing a wafer to form a plurality of functional chips integral with the wafer. A plurality of wafer tiles is defined in the wafer, wherein each wafer tile is composed of a cluster of functional chips. The wafer tiles are singulated by wafer dicing. A plurality of separate wafer tiles is bonded to a semiconductor wafer by hybrid bonding. The functional chips are singulated together with chips of the semiconductor wafer by dicing the bonded-together wafer tiles and semiconductor wafer.
