摘要： A diamond composite heat spreader having a low thermal mismatch stress can improve reliability and cost of diamond-based heat spreaders. A diamond composite heat spreader can have a thermally conductive base and a diamond film in thermal contact with the thermally conductive base. The diamond film and the thermally conductive base can have a residual thermal mismatch stress which is less than about 75% of a residual thermal mismatch stress which would result from forming the diamond film on the thermally conductive base using a high temperature deposition process at 700° C. The diamond film can be formed on the thermally conductive base using a low temperature vapor deposition process performed at a temperature from about 10° C to less than 700° C, and typically lower than about 450° C. The diamond films further have high thermal diffusivity and thermal conductivity which allow for dramatic improvements in heat transfer away from a heat source without the need for growing a thick diamond film. By providing a low temperature deposition of the diamond film, residual thermal mismatch stress can be significantly reduced, while allowing for use of well known heat spreaders such as standard copper heat spreaders and associated technologies.

摘要： A diamond composite heat spreader having a variable thermal conductivity gradient can improve control of heat transfer based on a specific application. A diamond-containing region of the heat spreader can contain diamond particles such that the diamond concentration and/or the diamond particle size a varied to produce a desired thermal conductivity gradient. Regions proximate to a heat source can have a higher thermal conductivity than regions further away from the heat source. Thin diamond films can also be used in conjunction with the particulate diamond in order to provide a region of maximum thermal conductivity adjacent a heat source. By providing a variable thermal conductivity gradient, more expensive materials such as diamond film and larger diamond particles can be selectively used in regions closer to a heat source, while allowing for cheaper smaller diamond particles and materials to be used farther away from the heat source where thermal conductivity can be lower without sacrificing overall performance.

摘要： The present invention provides diamond tools, and a method for the formation thereof, using CVD techniques. In one aspect, a mold is provided which has an interface surface configured to inversely match a configuration intended for the working surface of a diamond layer in a tool. After the mold is provided, various CVD techniques may be used to deposit diamond layers upon the diamond interface surface of the mold. Following diamond deposition upon the diamond interface surface, the mold may be removed by various means, such as chemical etching, or the mold may be left intact for certain applications, such as SAW filters. Thus, the working surface of the diamond receives a shape which inversely corresponds to the configuration of the mold's diamond interface surface. The diamond layer may then be incorporated into a tool, if such incorporation has not yet taken place.

摘要： Superabrasive cutting elements, backed compacts and methods for their manufacture are disclosed wherein metal coated superabrasive particles are cemented under HPHT conditions. The superabrasives bond to the metal of the coating and the metal coatings of adjacent particles bond to each other forming a matrix. A binding aid with thermal expansion characteristics close to that of the superabrasive particle can be infiltrated through or otherwise mixed with the particles to assist in the bonding between the metal coatings and to fill in voids. Catalyst and non-catalyst binding aids can also be used. Uncoated, smaller superabrasive particles can be interstitially dispersed among the coated particles to increase the superabrasive concentration and can self bond to form a cemented/sintered structure. Tungsten is a preferred metal coating and silicon is a preferred binding/sintering aid. The superabrasive can be diamond, cubic boron nitride, boron doped diamond or crushed, sintered polycrystalline aggregates. The free-standing cutting element can have a brazeable layer and the compact can be backed with, for example, cemented tungsten carbide. Free-standing cutting elements can be thermally stable up to 1,200.degree. C. Backed compacts can be thermally stable up to 1,100.degree. C.
