Abstract

A high thermal conductivity substrate is formed by making a sintered diamond composite and thereafter modifying the electrical properties of the composite by leaching graphite and other non-diamond materials from the composite and subsequently infusing the leached composite with material having known electrical properties. Alternatively, a diamond composite having high thermal conductivity known electrical properties if prepared and subsequently leached to remove graphite and other materials which interfere with the known electrical properties of the composite material.
