Patent ID: 8792239

Claim:
A power module package comprising: a base substrate made of a metal material; cooling channels formed to allow a cooling material to flow in an inner portion of the base substrate; an anodized layer formed on an outer surface of the base substrate; a metal layer formed on a first surface of the base substrate having the anodized layer and including circuits and connection pads; and semiconductor devices mounted on the metal layer, wherein the cooling channel includes: an introduction part having the cooling material introduced therethrough; a path part connected to the introduction part to thereby allow the introduced cooling material to pass therethrough; and a discharge part connected to the path part to thereby allow the cooling material to be discharged therethrough, wherein when the path part includes a plurality of paths, the plurality of paths are formed to be in proportion to a heat generation amount of the semiconductor devices, and the plurality of formed paths are disposed under areas in which the semiconductor devices are mounted.
