Abstract

A heat conducting support on which an electrical component can be mounted so as to conduct heat generated by the component away from the component. The support includes a substrate of good heat conducting material and a diamond body embedded in the substrate with a surface of the diamond body being flush with a surface of the substrate. A metal film extends over the surface of the substrate and the diamond body and is strongly adhered to the substrate. An electrical component can be mounted on and secured to the metal film over the diamond body. The support is formed by placing the diamond body on the surface of a plate of the material of the substrate and coating the surface of the plate around the diamond body with additional material of the substrate. The coating contacts the peripheral edge of the diamond body to secure the diamond body to the substrate and extends to the surface of the diamond body. A metal film can then be deposited on the surface of the diamond body and the coating.

Claims

2. A support in accordance with claim 1 in which the substrate comprises a base and a metal layer on the base, said metal layer surrounding the periphery of the diamond body and providing the surface which is flush with the surface of the diamond body.

3. A support in accordance with claim 2 in which the base is of a metal.

4. A support in accordance with claim 2 in which the base is of a ceramic.
