Abstract:
In a method for fabricating a flip-chip light emitting diode device, epitaxial layers (14, 114) are deposited on a growth substrate (16, 116) to produce an epitaxial wafer. A plurality of light emitting diode devices are fabricated on the epitaxial wafer. The epitaxial wafer is diced to generate a device die (10, 110). The device die (10, 110) is flip chip bonded to a mount (12, 112). The flip chip bonding includes securing the device die (10, 110) to the mount (12, 112) by bonding at least one electrode (20, 22, 120) of the device die (10, 110) to at least one bonding pad (26, 28, 126) of the mount (12, 112). Subsequent to the flip chip bonding, a thickness of the growth substrate (16, 116) of the device die (10, 110) is reduced.
