  • Patent number: 10618814
    Abstract: Diamond bodies and methods of manufacture are disclosed. Diamond bodies are formed from at least a bimodal, alternatively a tri-modal or higher modal, feedstock having at least one fraction of modified diamond particles with a fine particle size (0.5-3.0 ?m) and at least one fraction of diamond particles with coarse particle size (15.0 to 30 ?m). During high pressure—high temperature processing, fine particle sized, modified diamond particles in the first fraction preferentially fracture to smaller sizes while preserving the morphology of coarse particle sized diamond particles in the second fraction. Diamond bodies incorporating the two fractions have a microstructure including second fraction diamond particles dispersed in a continuous matrix of first fraction modified diamond particles and exhibit improved wear characteristics, particularly for wear associated with drilling of geological formations.

  • Patent number: 9970104
    Abstract: Provided is a coated tool exhibiting enhanced wear resistance and adhesiveness of an aluminum oxide layer and superior wear resistance and defect resistance. A cutting tool (1) in which at least a titanium carbonitride layer (8) and an aluminum oxide layer (10) having an ?-type crystalline structure are laminated in that order on a surface of a substrate (5). A surface-side Tc(116) in a surface-side peak is greater than a substrate-side Tc(116) in a substrate-side peak where Tc(116) is an orientation factor of the aluminum oxide layer (10) when comparing the substrate-side peak detected by measuring a portion on a substrate (5) side of the aluminum oxide layer (10) and the surface-side peak detected by measuring a portion on a surface side of the aluminum oxide layer (10) in X-ray diffraction analysis of the aluminum oxide layer (10).

    Abstract: A seamless hexagonal h-BN atomic monolayer thin film has a pseudo-single crystal structure including a plurality of h-BN grains that are seamlessly merged. Each of the h-BN grains has a dimension in a range from about 10 ?m to about 1,000 ?m. The seamless hexagonal boron nitride (h-BN) atomic monolayer thin film may be fabricated by a process including pre-annealing a metal thin film at a first temperature in a chamber while supplying hydrogen gas to the chamber; supplying nitrogen source gas and boron source gas to the chamber; and forming the seamless h-BN atomic monolayer thin film having a pseudo-single crystal atomic monolayer structure having a grain dimension in a range from about 10 ?m to about 1,000 ?m by annealing the pre-annealed metal thin film at a second temperature.

  • Patent number: 9914852
    Abstract: The present disclosure provides a method for reducing large particle counts (LPCs) in copper chemical mechanical polishing slurry by way of using high purity removal rate enhancer (RRE) in the slurry. The conductivity of the RRE in deionized water solutions correlates very strongly with the number of LPCs in the RRE, and thus in a slurry using the RRE.

  • Patent number: 9881803
    Abstract: The present disclosure relates to a method of performing a chemical mechanical planarization (CMP) process with a high germanium-to-oxide removal selectivity and a low rate of germanium recess formation. The method is performed by providing a semiconductor substrate having a plurality of germanium compound regions including germanium interspersed between a plurality of oxide regions including an oxide. A slurry is then provided onto the semiconductor substrate. The slurry has an oxidant and an etching inhibitor configured to reduce a removal rate of the germanium relative to the oxide. A CMP process is then performed by bringing a chemical mechanical polishing pad in contact with top surfaces of the plurality of germanium compound regions and the plurality of oxide regions.
