Patent ID: 8759122

Claim:
A method for making a light emitting chip package, comprising: providing a substrate with a top surface and a bottom surface; forming a plurality of recesses on the bottom surface of the substrate; forming an etch stop layer on the bottom surface, the etch stop layer traversing the recesses; forming a step hole on the top surface and exposing the etch stop layer at the top surface side of the substrate; forming an insulation layer on the top surface, the insulation layer traversing the step hole; defining a plurality of first through holes in each of the portions of the insulation layer and a plurality of second through holes in each of the portions of the etch stop layer, the number of the first through holes being different from the number of the second through holes, the first through holes in the insulation layer being communicated to the second through holes in the etch stop layer; filling the plurality of the first through holes and the second through holes with metal to respectively form a plurality of first electrical conductor portions and a plurality of second electrical conductor portions, the first electrical conductor portions being in contact with corresponding second electrical conductor portions; forming a plurality of metallic thermal conductors respectively on portions of the etch stop layer received in the recesses; forming a patterned electric conductive layer on the insulation layer, the electric conductive layer having two first electrodes and a second electrode; arranging a light emitting chip on the second electrode and wire bonding the light emitting chip to the two first electrodes; and encapsulating the light emitting chip with an encapsulation.
