An improved plasma enhanced chemical vapor deposition (CVD) reactor is provided for the synthesis of diamond and other high temperature materials such as boron nitride, boron carbide and ceramics containing oxides, nitrides, carbides and borides, or the like. An aspect of the present method enables a plasma to substrate distance to be optimized for a given surface. This has been found to enable a substantially uniform thin film coating of diamond or like material to be deposited over a substrate.

A novel apparatus and method for the cyclic growth-etch deposition of diamond on a substrate by flame chemical vapor deposition (CVD) is developed. The cyclic growth-etch diamond deposition is accomplished by placing a suitable substrate to be coated under a CVD flame and providing a disk or face plate or other shapes having one or more teeth (or holes) wherein upon rotation of the disk, or face plate, or other shape, the teeth attached to the disk, or face plate, or other shape obstruct the path of the CVD flame from contacting the substrate at a desired time scale of .tau..sub.growth and t.sub.cycle to produce high quality (FWHM of 1-3.5 cm.sup.-1) diamond.

Infrared lasers are used to deposit diamond thin films onto a substrate. In one embodiment, the deposition of the film is from a gas mixture of CH.sub.4 and H.sub.2 that is introduced into a chemical vapor deposition chamber and caused to flow over the surface of the substrate to be coated while the laser is directed onto the surface. In another embodiment, pure carbon in the form of soot is delivered onto the surface to be coated and the laser beam is directed onto the surface in an atmosphere that prevents the carbon from being burned to CO.sub.2.

To provide a diamond film body which can be provided easily on various components, a diamond film component which has a diamond film body fixed thereon, and a production method of them. 
SOLUTION: A diamond film body 1 is produced, which includes a diamond film 3 formed by vapor phase synthesis on the surface of a substrate which is removed after forming a plating layer, and a plating layer 4 formed on the surface of the diamondfilm 3. Further, a diamond film component is produced by fixing the plating layer of the diamond film body 1 and the surface of the component by adhesion means such as an adhesive

A diamond film is deposited on a surface of a substrate. The diamond film is attached securely to the substrate by forming a first layer on the surface comprising a mixture of a main component of the substrate and a sintering reinforcement agent for diamond, then forming a second layer comprising a mixture of said agent and diamond on said first layer, and finally forming the diamond film on the second layer.

Diamonds are used to nucleate diamond and diamond-like carbon films in a chemical vapor deposition process using bias enhancement. A negative bias is applied to the substrate, such that a cationic form of the diamond is accelerated toward the substrate during the nucleation phase of the deposition. In this manner, the diamondoid may be embedded or partially embedded in the substrate and/or growing film, increasing the adhesion of the film to the substrate. According to the present embodiments, it is not necessary to mechanically pre-seed the substrate for nucleation purposes.

Provided is a method for producing a thin film, whereby it becomes possible to achieve both the reduction in concentration of carbon impurities and a high film formation speed and it also becomes possible to produce different crystal structures in accordance with the intended use steadily. According to the present invention, a method for producing an oxide crystal thin film is provided, which comprises a step of supplying raw material microparticles into a film formation chamber by the action of a carrier gas to form an oxide crystal thin film on a film formation sample placed in the film formation chamber, wherein the raw material microparticles are produced by transforming a raw material solution, which is a solution comprising a gallium compound and/or an indium compound and water, into microparticles, and wherein the gallium compound and/or the indium compound is a bromide or an iodide.

Iron nanoparticles were employed to induce the synthesis of diamond on molybdenum, silicon, and quartz substrates. Diamond films were grown using conventional conditions for diamond synthesis by hot filament chemical vapor deposition, except that dispersed iron oxide nanoparticles replaced the seeding. This approach to diamond induction can be combined with dip pen nanolithography for the selective deposition of diamond and diamond patterning while avoiding surface damage associated to diamond-seeding methods.
