Patent ID: 8147927

Claim:
A method of making a multilayered structure, comprising: growing a diamond layer on a substrate, wherein the bottom surface of the diamond rests on the substrate; applying a first thin adhesion layer on the top surface of the diamond layer; applying a first metal layer having a thermal conductivity greater than 200 W/m-K and a coefficient of thermal expansion greater than 12 ppm/K on the first thin adhesion layer; removing the substrate; applying a second thin adhesion layer on the bottom surface of the diamond layer; and applying a second metal layer having a thermal conductivity greater than 200 W/m-K and a coefficient of thermal expansion greater than 12 ppm/K on the second thin adhesion layer, wherein a CTE matching equation determines the thickness of the diamond layer, the first metal layer, and the second metal layer such that the CTE of the multilayered structure matches the CTE of a semiconductor, wherein the thickness of each of the first and second thin adhesion layers is less than 10% compared to the thickness of each of the first and second metal layers.
