Abstract
An insulated substrate having high thermal conductivity comprising a substrate having a thermal conductivity of not less than 50 W/m.k., and an insulating layer having high thermal conductivity coated on the substrate; and a method of producing the insulated substrate characterized in that an insulating layer is formed on a substrate by applying DC voltage and RF power to the substrate and providing a magnetic field parallel to the surface of the substrate. The insulated substrate has good heat conductivity, thermal resistance and smooth surface, whereby exfoliation can be prevented.
