Abstract

Embodiments relate to transferring dies or other electronic components from a carrier substrate to a target substrate of a device as part of chip assembly for the device. Bonding material is applied to selected dies on a carrier substrate by direct boning, or to corresponding die transfer locations on a target substrate. The carrier substrate is then brought into contact with the target substrate to transfer each of the selected dies to the carrier substrate. Dies can also be directly bonded to the target substrate even in the presence of other die in situ (e.g., from a previous bonding cycle), hence, enables more than one direct bond cycle to be carried out for a target substrate. As such, multi-color (RGB) display elements can be assembled in stages (e.g., separate bonding cycles) in a flexible manner to provide redundancy or to replace inoperative LED dies.
