Abstract

What is disclosed is structures and methods to integrate microdevices into system or receiver substrates. The integration of microdevices is facilitated by adding staging pads to microdevices before or after transferring. Creating stages after the transfer of a first microdevice to a substrate for the subsequent microdevice transfer to the first (or the second) microdevice transfer. The stage improves the surface profile of the substrate so that next microdevice can be transferred without the first microdevice on the substrate get damaged by or interfere with the surface of the donor or transfer head. Some embodiments further relate to tiled display device and more particularly, to stacking tiles to a backplane to form the tiled display device.
