Provided are a structure for producing a high-quality single crystal diamond, and a method for manufacturing the structure for producing diamond. A structure for producing a diamond is composed of a base substrate and an Ir thin film formed on the base substrate. The thermal expansion coefficient of the base substrate is 5 times or less of the thermal expansion coefficient of diamond and the melting point of the base substrate is 700 C. or higher. The peak angle in the X-ray diffraction pattern of the Ir thin film is different from the peak angle in the X-ray diffraction pattern of the base substrate.

Methods of depositing an adamantane film are described, which may be used in the manufacture of integrated circuits. Methods include processing a substrate in which an adamantane seed layer is deposited on a substrate, converting to a diamond nuclei layer having an increased crystallinity relative to the adamantane seed layer and then grown into full nanocrystalline diamond film from the diamond nuclei layer.
