Abstract: 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.

Abstract: Disclosed is a gas decomposition apparatus for decomposing many kinds of foul-smelling gas, which is free from safety problems while applying a relatively high voltage between anode and cathode. A method for decomposing gas is also disclosed. The gas decomposition apparatus is characterized by comprising a porous catalyst electrode (6) containing a catalyst, a counter electrode (7) forming a pair with the catalyst electrode, and an ion-conductive electrolyte (15) sandwiched between the catalyst electrode and the counter electrode. The gas decomposition apparatus is also characterized in that the catalyst is supported by a carrier which is composed of a conductive material and held by the catalyst electrode, or directly supported by the catalyst electrode, and the conductive material in contact with the catalyst in the catalyst electrode is not a non-covalent bond carbon material.

Abstract: A method and an apparatus for forming a diamond film from microwave plasma by controlling a manufacturing condition based on spectroscopic measurement of plasma emission to obtain a large area of a high-quality diamond film. In the method of forming a diamond film, a gas mixture of hydrocarbon gas and hydrogen gas is introduced into a reactor, where the gas mixture is excited by microwave which is also introduced into the reactor to generate plasma, and the light emitted from the plasma is spectroscopically measured. Furthermore, a formation condition of the diamond film is controlled such that the spectrum of a carbon molecule (C2) falls within a predetermined range of requirement.

In the method of forming a diamond film, a gas mixture of a hydrocarbon gas and hydrogen gas is introduced into a reactor (7), and the gas mixture is excited by microwaves, which are also introduced into the reactor (7), to generate plasma. The light emitted from the plasma is then measured by spectroscopic means.

Abstract: A method of manufacturing n -type semiconductor diamond by the present invention is characterized in producing diamond incorporating Li and N by implanting Li ions into, so that 10 ppm thereof will be contained in, single-crystal diamond incorporating 10 ppm or more N , or else, in doping single-crystal diamond with Li and N ions, by implanting the ions so that ion-implantation depths at which the post-implantation Li and N concentrations each are 10 ppm or more will overlap, and thereafter annealing the diamond in a temperature range of from 800°C or more to less than 1800°C to electrically activate the Li and N and restore the diamond crystalline structure. In the present invention, n -type semiconductor diamond incorporates, from the surface of the crystal to the same depth, 10 ppm or more of each of Li and N, wherein its sheet resistance is 10 7 ©/¡ or less.

Abstract: An n-type diamond epitaxial layer 20 is formed by processing a single-crystalline ä100ü diamond substrate 10 so as to form a ä111ü plane, and subsequently by causing diamond to epitaxially grow while n-doping the diamond ä111ü plane. Further, a combination of the n-type semiconductor diamond, p-type semiconductor diamond, and non-doped diamond, obtained in the above-described way, as well as the use of p-type single-crystalline ä100ü diamond substrate allow for a pn junction type, a pnp junction type, an npn junction type and a pin junction type semiconductor diamond to be obtained.
