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.
