Original Abstract Submitted
Optoelectronic structures and methods of formation are described. In an embodiment, an optoelectronic structure includes a backplane with a driving circuitry and an array of contact pads, and a device layer bonded to the backplane. The device layer may include an array of micro-sized diodes and landing pads, and a reconstituted wiring layer including an array of via contacts connected to the array of landing pads. The reconstituted wiring layer can be directly bonded with the array of contacts with metal-metal bonds. A placement distribution of the array of landing can be decoupled from a position distribution of the array of via contacts.
