    摘要： A method for synthesizing diamond by chemical vapor deposition (CVD) is described. The method produces diamond of high purity and high crystallizability having various uses at low cost and at high speed. In a first method, a mixture of oxygen gas and a carbon-containing compound gas, and optionally an inert gas, is introduced into a reaction vessel. In a second method, a mixture containing at least one of fluorine gas, chlorine gas, a nitrogen oxide gas, sulfur dioxide, an aforementioned mixture of oxygen gas and a carbon-containing compound gas, or a mixture thereof with an inert gas is introduced into the reaction vessel. A plasma is generated by use of an electromagnetic field, thereby producing diamond on a base material placed in the vessel.

    摘要： An X-ray window having a diamond X-ray transparent film, diamond reinforcing crosspieces and a substrate on which the diamond X-ray transparent film has been grown. As reinforcing crosspieces are made of diamond, no thermal stress is generated between the X-ray transparent film and the crosspieces. This mask excels in flatness, transmittance of X-rays, and strength.

    摘要： An X-ray lithography mask comprising a X-ray transparent film made from diamond, X-ray absorber patterns deposited on the X-ray transparent film and diamond crosspieces shaped on the diamond X-ray transparent film for reinforcing the diamond X-ray transparent film. Since both the transparent film and the reinforcing crosspieces are made from diamond, no thermal stress is induced by the change of temperature. The mask excels in transmittance for X-ray, flatness and strength.

    摘要： A diamond heat sink having a very high thermal property, to be used for radiation of semiconductor devices or compressors, includes a plate-shaped diamond substrate and fins for increasing the thermal property. The fins are combined with the substrate and are of a material having a heat conductivity of at least 1 (W/cm.multidot.K), for example, diamond. Such heat sink is produced by a simple process including arranging a base material and fins for growing diamond in such a manner that the surface of the base material and the upper ends of the fins are substantially the same height by the use of a suitable supporting member or by working the base material itself and growing diamond thereon by a gaseous phase synthesis method.
