    摘要: Diamond material made by a hot filament chemical vapor deposition process, providing large film area, good growth rate, phase purity, small average grain size, smooth surfaces, and other useful properties. Low substrate temperatures can be used. Control of process variables such as pressure and filament temperature and reactant ratio allow control of the diamond properties. Applications include MEMS, wear resistance low friction coatings, biosensors, and electronics.

    摘要: A method of depositing nanocrystalline diamond film on a substrate at a rate of not less than about 0.2 microns/hour at a substrate temperature less than about 500° C. The method includes seeding the substrate surface with nanocrystalline diamond powder to an areal density of not less than about 1010sites/cm2, and contacting the seeded substrate surface with a gas of about 99% by volume of an inert gas other than helium and about 1% by volume of methane or hydrogen and one or more of acetylene, fullerene and anthracene in the presence of a microwave induced plasma while maintaining the substrate temperature less than about 500° C. to deposit nanocrystalline diamond on the seeded substrate surface at a rate not less than about 0.2 microns/hour. Coatings of nanocrystalline diamond with average particle diameters of less than about 20 nanometers can be deposited with thermal budgets of 500° C.-4 hours or less onto a variety of substrates such as MEMS devices.

    摘要: A monolithically integrated 3-D membrane or diaphragm/tip (called 3-D tip) of substantially all UNCD having a tip with a radius of about less than 50 nm capable of measuring forces in all three dimensions or being used as single tips or in large arrays for imprint of data on memory media, fabrication of nanodots of different materials on different substrates and many other uses such as nanolithography production of nanodots of biomaterials on substrates, etc. A method of molding UNCD is disclosed including providing a substrate with a predetermined pattern and depositing an oxide layer prior to depositing a carbide-forming metallic seed layer, followed by seeding with diamond nano or micropowder in solvent suspension, or mechanically polishing with diamond powder, or any other seeding method, followed by UNCD film growth conforming to the predetermined pattern. Thereafter, one or more steps of masking and/or etching and/or coating and/or selective removal and/or patterning and/or electroforming and/or lapping and/or polishing are used in any combination to form the tip or probe.
