Patent ID: 8472196

Claim:
A power module, comprising: a first heat sink having a first area and a second area; a first power chip disposed in the first area; a thermo-conductive insulating layer disposed in the second area, wherein the thermo-conductive insulating layer includes a thermo-conductive layer, an insulating layer and a trace layer; a second power chip disposed on the first heat sink through the thermo-conductive insulating layer, wherein the first power chip and the second power chip have at least two electrodes, respectively, and the second power chip is a vertical-type power chip; a lead frame electrically connected to at least one of the electrodes of the first power chip and the second power chip respectively to form at least two pins; and a molding compound covering the first power chip, the thermo-conductive insulating layer, the second power chip and a portion of the lead frame, wherein one of the electrodes of the second power chip is directly connected to the trace layer of the thermo-conductive insulating layer, wherein the first heat sink is electrically connected to the first power chip and form a common connection point, the common connection point of the first heat sink and the first power chip is a voltage static location.
