Abstract:
A method of fabricating a substrate free light emitting diode (LED), includes arranging LED dies on a tape to form an LED wafer assembly, molding an encapsulation structure over at least one of the LED dies on a first side of the LED wafer assembly, removing the tape, forming a dielectric layer on a second side of the LED wafer assembly, forming an oversized contact region on the dielectric layer to form a virtual LED wafer assembly, and singulating the virtual LED wafer assembly into predetermined regions including at least one LED. The tape can be a carrier tape or a saw tape. Several LED dies can also be electrically coupled before the virtual LED wafer assembly is singulated into predetermined regions including at the electrically coupled LED dies.
