昭58−911001同59−3098等)。Artificially produced synthetic diamonds include sintered diamond and diamond films produced by the CVD method. Diamond films can be produced relatively easily, and many manufacturing techniques have been published (for example, in JP-A (Sho 58-911001, Sho 59-3098, etc.).

たガスを10〜30ae/sinの速度で導入する。The basic hot filament CVD method involves heating a tungsten filament with electricity to make it incandescent in a hydrocarbon gas atmosphere diluted with hydrogen, placing a substrate such as a silicon wafer directly below it, and depositing a diamond thin film on the substrate surface. The general conditions are: filament temperature [1800 to 2200''C, distance between filament and substrate surface 5 to 20 mm, pressure 30 Torr, and raw material gas: methane diluted 100 to 200 times with hydrogen. The gas is introduced at a rate of 10 to 30 ae/sin.

は、基板を回転させる等の工夫が必要であった。By the way, in the above-mentioned conventional hot filament CVD method, when the distance between the curtain plate and the filament is set to 5 m+, for example, diamond can be uniformly deposited on the substrate surface in an area with a diameter of about 5 m, and diamond can be deposited uniformly on a larger area. In order to deposit, it was necessary to take measures such as rotating the substrate.

作製した。Implementation Example 12 As shown in Figure 3, two filaments 12 were provided with an interval of 5 INR, the mesh 13 was semi-cylindrical, the filament 12 was heated to 1800°C, and the mesh 13 was heated to 1700°C.
A diamond end film was produced in the same manner as in Example 1 except that the temperature was changed to .degree.

This film was confirmed to be diamond by X-ray diffraction analysis and Raman spectroscopy. The production rate of this die-pulled 7-mond sample was 14 μvL/h.

長所を右りる。As described above, in the method of the present invention, a mesh of a high melting point metal is electrically heated and electron beam heating is used in combination, so that the mesh can be heated uniformly and the raw material gas can be excited in a wide space. Furthermore, the electron beam passing through the mesh excites the surface of the base material, and the rate of diamond precipitation is maintained at a high rate over a wide area. Furthermore, by adapting the shape of the mesh to the 1u11 surface, there are many advantages, such as the ability to uniformly coat materials on curved surfaces.
