Patent ID: 8624388

Claim:
A package carrier suitable for carrying a heat-generating element, the package carrier comprising: an insulating layer having an upper surface, a lower surface opposite to the upper surface, and a first opening connecting the upper surface and the lower surface; a patterned conductive layer formed of a single layered metal film and contact with the upper surface of the insulating layer, wherein the patterned conductive layer has a third opening, and the third opening coincides with the first opening; a thermal conductive block configured on the lower surface of the insulating layer and having a top surface, a bottom surface opposite to the top surface, and a plurality of second openings, wherein the first opening and the third opening expose a portion of the top surface of the thermal conductive block to define a device bonding region, and the second openings do not communicate with the first opening; and a surface passivation layer entirely covering the patterned conductive layer and the portion of the top surface of the thermal conductive block exposed by the first opening and the third opening, the heat-generating element being configured on the surface passivation layer correspondingly located above the device bonding region.
