Patent ID: 11876034
Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLC
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A power module comprising:
a first stack of layers comprising a first semiconductor die, a second semiconductor die and a first center spacer layer disposed between the first semiconductor die and the second semiconductor die, wherein the first center spacer layer is ‘C’-shaped or cup shaped;
a first heat pipe extending at least partially into an open end of the first center spacer layer and receiving thermal energy from the first semiconductor die and the second semiconductor die;
a second stack of layers transferring thermal energy away from the first semiconductor die and comprising a first conductive layer, a second conductive layer, and a first dielectric layer disposed between the first conductive layer and the second conductive layer; and
a third stack of layers transferring thermal energy away from the second semiconductor die and comprising a third conductive layer, a fourth conductive layer, and a second dielectric layer disposed between the third conductive layer and the fourth conductive layer,
wherein
the first stack of layers is disposed between the second stack of layers and the third stack of layers, and
the second stack of layers, the third stack of layers and the first heat pipe facilitate dual sided cooling of each of the first semiconductor die and the second semiconductor die.
