    Abstract: A hard coating includes two first crystalline phases, and a second crystalline phase containing AlN of a wurtzite-type crystal structure disposed therebetween. The two first crystalline phases each include, independently, a laminate structure having a Ti1-x1Alx1N phase having a sodium chloride-type crystal structure, and an Alx2Ti1-x2N phase having a sodium chloride-type crystal structure that are alternately stacked. An Al composition ratio x1 satisfies a relationship 0.5?x1?0.75, and an Al composition ratio x2 satisfies a relationship 0.75<x2?0.95. The laminate structure includes a region in which an Al concentration periodically changes along a stacking direction of the Ti1-x1Alx1N phase and the Alx2Ti1-x2N phase. In this region, a difference between a maximum value of the Al composition ratio x2 and a minimum value of the Al composition ratio x1 is greater than 0.25.

  • Patent number: 10316431
    Abstract: The present invention provides a method of growing an ingot of group III nitride. Group III nitride crystals such as GaN are grown by the ammonothermal method on both sides of a seed to form an ingot and the ingot is sliced into wafers. The wafer including the first-generation seed is sliced thicker than the other wafers so that the wafer including the first-generation seed does not break. The wafer including the first-generation seed crystal can be used as a seed for the next ammonothermal growth.

  • Patent number: 10186630
    Abstract: Embodiments relate to fabricating a wafer including a thin, high-quality single crystal GaN layer serving as a template for formation of additional GaN material. A bulk ingot of GaN material is subjected to implantation to form a subsurface cleave region. The implanted bulk material is bonded to a substrate having lattice and/or Coefficient of Thermal Expansion (CTE) properties compatible with GaN. Examples of such substrate materials can include but are not limited to AlN and Mullite. The GaN seed layer is transferred by a controlled cleaving process from the implanted bulk material to the substrate surface. The resulting combination of the substrate and the GaN seed layer, can form a template for subsequent growth of overlying high quality GaN. Growth of high-quality GaN can take place utilizing techniques such as Liquid Phase Epitaxy (LPE) or gas phase epitaxy, e.g., Metallo-Organic Chemical Vapor Deposition (MOCVD) or Hydride Vapor Phase Epitaxy (HVPE).
