A substrate for mounting a flip-chip on a metallized circuit on the upper surface of the substrate. The substrate is silicon carbide condensed on a graphite or silicon core. The upper surface of the silicon carbide has a layer of insulating material comprised of silicon oxide, silicon nitride, aluminum nitride, boron nitride, an organic insulator such as polyimide, and diamond. The insulator prevents inadvertent shorting of the integrated circuit. The insulating layer can be deposited on the silicon carbide by such processes as chemical vapor deposition, sputtering, spinning or roller coating.
