Patent ID: 8587009

Claim:
A light emitting chip package, comprising: a substrate; an insulation layer arranged on a top surface of the substrate; a patterned electric conductive layer partially covering the insulation layer; a light emitting chip arranged on the electric conductive layer; an encapsulation covering the light emitting chip and the electric conductive layer; an etch stop layer arranged on a bottom surface of the substrate, a plurality of portions of the etch stop layer in contact with a corresponding plurality of portions of the insulation layer; a corresponding plurality of thermal conductors formed on the etch stop layer at the bottom surface of the substrate at the portions of the etch stop layer; and a plurality of electrical conductors penetrating the insulation layer and the etch stop layer and connecting the electric conductive layer with the thermal conductors, the plurality of electrical conductors being isolated from each other; wherein a plurality of first through holes is defined in each of the portions of the insulation layer, a plurality of second through holes is defined in each of the portions of the etch stop layer, and the number of first through holes is different from the number of second through holes; and the plurality of electrical conductors comprises a plurality of first electrical conductor portions filled in the first through holes, respectively, and a plurality of second electrical conductor portions filled in the second through holes, respectively, and the first electrical conductor portions are in contact with corresponding second electrical conductor portions.
