Abstract

Official abstract text for this publication.

Disclosed is a power module with double-sided cooling, comprising a semiconductor chip disposed between an upper substrate and a lower substrate; a first power lead disposed between the upper substrate and the semiconductor chip; a signal lead disposed between the upper substrate and the semiconductor chip, and spaced apart from the first power lead; a second power lead disposed between the lower substrate and the semiconductor chip; and a separation plate disposed between the first power lead, the signal lead, and the semiconductor chip; wherein the separation plate connects the first power lead with the semiconductor chip via a first hole formed through the separation plate, and connects the signal lead and the semiconductor chip via a second hole formed through the separation plate.

First claim

Opening claim text (preview).

What is claimed is: 1. A power module with double-sided cooling, comprising: a semiconductor chip disposed between an upper substrate and a lower substrate; a first power lead disposed between the upper substrate and the semiconductor chip; a signal lead disposed between the upper substrate and the semiconductor chip, and spaced apart from the first power lead; a second power lead disposed between the lower substrate and the semiconductor chip; and a separation plate disposed between the first power lead, the signal lead, and the semiconductor chip, wherein the separation plate connects the first power lead with the semiconductor chip via a first hole formed through the separation plate, and connects the signal lead and the semiconductor chip via a second hole formed through the separation plate. 2. The power module of claim 1 , wherein an inner circumferential surface of the second hole disposed in the separation plate is coated with a conductive layer. 3. The power module of claim 1 , wherein the first hole provided in the separation plate is filled with a solder material to connect the first and second power leads with the semiconductor chip. 4. The power module of claim 1 , wherein the separation plate has a thickness of from about 100 to about 200 μm. 5. The power module of claim 1 , wherein the separation plate is made of a dielectric material or a ceramic material. 6. The power module of claim 2 , wherein the conductive layer is a copper plating layer. 7. The power module of claim 2 , wherein the conductive layer has a thickness of from about 1 to about 10 μm. 8. The power module of claim 2 , wherein the conductive layer extends from the inner circumferential surface of the second hole to a top surface of the separation plate. 9. The power module of claim 2 , wherein a lower portion of the second hole disposed in the separation plate is filled with a solder material to connect the conductive layer with the semiconductor chip.
