A power module includes a first heat sink, first and second power chips, a thermo-conductive insulating layer, a lead frame and a molding compound. The first heat sink has a first area and a second area. The first power chip is disposed in the first area. The thermo-conductive insulating layer is disposed in the second area. The second power chip is disposed on the heat sink through the thermo-conductive insulating layer. The lead frame is electrically connected to at least one of the first and second power chips. The molding compound covers the first and second power chips, the thermo-conductive insulating layer and a portion of the lead frame. The first heat sink is electrically connected to at least one of the first and second power chips. Because the first power chip is not disposed on the first heat sink through the thermo-conductive insulating layer, the cost can be reduced.
