Abstract
Embodiments relate to mass-transfer methods useful for fabricating products containing Light Emitting Diode (LED) structures. LED arrays are transferred from a source substrate to a target substrate by beam-assisted release (BAR) of a plurality of LED devices in a high-speed flexible manner. The BAR mass-transfer approach is also able to utilize a Known Good Die (KGD) data file of the source substrate to transfer only functionally good die and avoid rework and yield losses.
