Claim:
1. A method of manufacturing a light emitting diode package base comprising: providing a metal core substrate having a top surface, a bottom surface, and side surfaces; forming two first trenches in the metal core substrate, the first trenches extending from the top surface to the bottom surface; at least partially filling the first trenches with a first dielectric material to form dielectric isolations, the dielectric isolations dividing the metal core substrate into three metal core portions, wherein two of the metal core portions serve as the light emitting diode package electrodes, and wherein each outer portion of the light emitting diode package electrodes is one of the side surfaces of the metal core substrate; applying a second dielectric material to cover at least a portion of the first dielectric material; forming a first conductive layer over the second dielectric material to form circuit contacts, the first conductive layer including a first conductive material; forming second trenches extending from top surface of the conductive layer to the top surface of the metal core substrate; and partially filling the second trenches with a second conductive material to form conductive trenches.
