Disclosed herein is a power semiconductor module. The module includes metal plates each having a first through hole, with an anodic oxidation layer formed on a surface of metal plates and an interior of the first through hole. A cooling member has a second through hole at a position corresponding to the first through hole, and the metal plates are attached to both sides of the cooling member. A circuit layer is formed on the anodic oxidation layer and performs an interlayer connection through a via formed in the first and second through holes. A power device is connected to the circuit layer. A resin encapsulant encloses the circuit layer and the power device. A housing is installed to each of the metal plates to form a sealing space for the resin encapsulant.

Disclosed is a heat dissipating circuit board, which includes a metal core including an insulating layer formed on the surface thereof, a circuit layer formed on the insulating layer and including a seed layer and a first circuit pattern, and a heat dissipating frame layer bonded onto the circuit layer using solder and having a second circuit pattern, and in which the heat dissipating frame layer is bonded onto the circuit layer not by a plating process but by using solder, thus reducing the cost and time of the plating process and relieving stress applied to the heat dissipating circuit board due to the plating process. A method of manufacturing the heat dissipating circuit board is also provided.

A substrate for a light emitting diode (LED) package, and an LED package having the same are disclosed. The substrate for an LED package includes: a metal plate; an insulation oxide layer formed on a portion of the surface of the metal plate; a first conductive pattern formed at one region of the insulation oxide layer and providing a light emitting diode mounting area; and a second conductive pattern formed at another region of the insulation oxide layer such that it is separated from the first conductive pattern. In the substrate for an LED package, because regions of the insulation oxide layer other than regions for insulating conductive patterns are removed, heat generated from the light emitting diode can be effectively released. In addition, degradation of reflexibility and luminance of the LED due to the insulation oxide layer can be prevented.
