Claim:
1. A Light Emitting Diode (LED), comprising: a semiconductor LED die that includes an LED epi region and a substrate, the LED epi region having first and second opposing faces, a plurality of LED epi region sidewalls therebetween that extend obliquely from the second face toward the first face of the LED epi region to define an obtuse angle with the second face, and an anode contact and a cathode contact on the first face, the substrate having inner and outer faces and a plurality of substrate sidewalls therebetween that extend obliquely from the outer face toward the inner face of the substrate to define an obtuse angle with the outer face, the inner face of the substrate being adjacent the second face of the LED epi region; a carrier die that includes inner and outer faces and a plurality of carrier die sidewalls therebetween that extend obliquely from the inner face toward the outer face of the carrier die to define an obtuse angle with the inner face, and that is electrically connected to the anode and cathode contacts that are on the first face of the LED epi region of the LED die, wherein the LED epi region and the carrier die have sides that are within 100 μm of one another in length; and a phosphor layer having first and second opposing surfaces that both conformally extend on the outer face and the sidewalls of the substrate, on the plurality of LED epi region sidewalls and on the plurality of carrier die sidewalls, one of the first and second opposing surfaces being directly on the outer face and the sidewalls of the substrate, the plurality of LED epi region sidewalls and the plurality of carrier die sidewalls, the LED being free of a dome that extends on the semiconductor LED die and on the carrier die.
