Abstract
Diamond is used as an electrically insulating substrate in multi-layer devices. In a transformer, the first electrical conductor forms a coil. The first electrical conductor is formed in a plurality of layers. Electrical carriers are formed on a layer to make an electrical path around a core of ferrous material. The second conductor forms a second coil of the transformer and also wraps around the core of ferrous material. Using diamond is advantageous in a transformer since the diamond is very effective at transferring heat from the core. The diamond also electrically insulates the various portions of the transformer. An electronic packaging concept includes mounting one or more electronic components to a substrate including a layer of diamond. The layer of diamond is sufficient to transfer heat from the one or more electronic components attached to the diamond substrate. The entire substrate can also be made of diamond. Diamond is unique in that it is a good electrical conductor as well as a good thermal conductor.
