Abstract:
A surface mount LED package having a tight footprint and small vertical image size is fabricated by a method comprising: forming light emitting diode chips each having a substrate and a plurality of layers configured to emit electroluminescence responsive to electrical energizing; forming electrical vias in a sub mount, the electrical vias passing from a front side of the sub-mount to a back-side of the sub-mount; flip chip bonding the light emitting diode chips on the front-side of the sub mount such that each light emitting diode chip electrically contacts selected electrical vias; thinning or removing the substrates of the flip-chip bonded light emitting diode chips; and after the thinning, disposing a phosphor over the flip chip bonded light emitting diode chips.
