Abstract
A method of manufacturing light emitting diode (LED) devices is provided. In one example, the method comprises: forming a plurality of LED dies on a starter substrate, each of the plurality of LED dies including a device-side bump; moving, using a pick up tool (PUT), the starter substrate and the plurality of LED dies towards a backplane, the backplane including a plurality of backplane-side bumps; establishing the conductive bonds between the device-side bumps of the plurality of LED dies and the backplane-side bumps of the backplane at the plurality of contact locations; and operating the PUT to release the starter substrate to enable transferring of the plurality of LED dies to the backplane.
