Abstract
A multilayer substrate includes a diamond layer CVD grown on a composite layer. The composite layer includes particles of diamond and silicon carbide and, optionally, silicon. A loading level (by volume) of diamond in the composite layer can be ≧5%; ≧20%; ≧40%; or ≧60%. The multilayer substrate can be used as an optical device; a detector for detecting radiation particles or electromagnetic waves; a device for cutting, drilling, machining, milling, lapping, polishing, coating, bonding, or brazing; a braking device; a seal; a heat conductor; an electromagnetic wave conductor; a chemically inert device for use in a corrosive environment, a strong oxidizing environment, or a strong reducing environment, at an elevated temperature, or under a cryogenic condition; or a device for polishing or planarization of other devices, wafers or films.
