Abstract:
1. A method for fabricating a light emitting device comprising: providing a flip-chip light emitting diode (LED) die on a submount, there being a gap between the LED die and the submount, the LED die having a bottom surface facing the submount and a top surface opposite the bottom surface; molding an underfill material over the LED die so that the underfill material encapsulates the LED die and substantially completely fills the gap between the LED die and the submount; and removing the underfill material at least over a top surface of the LED die, wherein the LED die comprises epitaxial layers grown on a growth substrate, wherein a top surface of the growth substrate is the top surface of the LED die, wherein removing the underfill material comprises removing the underfill material from at least the top surface of the growth substrate.
