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 an in-process functional test Known-Good Die (KGD) driven mass-transfer of a plurality of LED devices in a high-speed flexible manner. Certain preferred embodiments using beam-addressed release (BAR) mass-transfer approaches are able to utilize a Known Good Die (KGD) data file of the source substrate in a manner that avoids additional steps, rework and yield losses.
