Claim:
1. A method of fabricating a substrate free light emitting diode (LED), comprising: disposing a wafer having a plurality of LED dies on a saw tape in a particular order; using a pick and place procedure to arrange the plurality of LED dies on a carrier tape to form an LED wafer assembly, wherein the plurality of LED dies are arranged on the carrier tape by grouping the LED dies such that each LED die within a group has a wavelength difference between LED dies that is within a predetermined threshold value, and wherein the LED wafer assembly is formed based on the grouping of the LED dies such that the LED dies in each group are all arranged on the carrier tape in a different order from the particular order on the saw tape; molding an encapsulation structure over at least one of the plurality of LED dies on a first side of the LED wafer assembly; removing the tape; and singulating the LED wafer assembly into predetermined regions comprising at least one LED.
