Claim:
A method of cooling a resistor, comprising: forming a substrate: forming a high thermal conductivity electrical insulator on a top surface of the substrate; forming a high conductivity insulator having a high thermal conductivity adjacent with and in direct thermal contact with the high thermal conductivity electrical insulator; forming a via hole in the high conductivity insulator such that a top surface of the high thermal conductivity electrical insulator is exposed through the high conductivity insulator; and forming a heat sink contact in the via hole and directly on top of the top surface of the high thermal conductivity electrical insulator such that the high conductivity insulator surrounds and directly contacts a lower section of the heat sink contact, wherein the direct contact of the heat sink contact with the high thermal conductivity electrical insulator forms a direct thermal contact between the heat sink contact and the high thermal conductivity electrical insulator such that heat is transferred directly between the heat sink contact and the high thermal conductivity electrical insulator; wherein the direct contact of the high conductivity insulator surrounding the lower section of the heat sink contact forms a direct thermal contact between the high conductivity insulator and the lower section of the heat sink contact such that heat is transferred directly between the high conductivity insulator and the lower section of the heat sink contact; and wherein the high thermal conductivity electrical insulator is in thermal contact with a resistor through the heat sink contact.
