Power module package having patterned insulation metal substrate
A power module package is provided, including a substrate, a first chip, and a second chip. The substrate includes a metal carrier, a patterned insulation layer disposed on the metal carrier and partially covering the metal carrier, and a patterned conductive layer disposed on the patterned insulation layer. The first chip is disposed on the metal carrier not covered by the patterned insulation layer. The second chip is disposed on the patterned conductive layer and electrically connected to the first chip.
1. A method of manufacturing a patterned insulation metal substrate, comprising:
providing a substrate including an insulation layer and a patterned conductive layer covering a top surface of the insulation layer;
forming an adhesive side on a bottom surface of the insulation layer;
forming an opening through the insulation layer; and
laminating a patterned metal carrier to the adhesive side of the insulation layer.
