摘要： Carbon nanotubes are formed on a surface of a substrate using a plasma chemical deposition process. After the nanotubes have been grown, a post-treatment step is performed on the newly formed nanotube structures. The post-treatment removes graphite and other carbon particles from the walls of the grown nanotubes and controls the thickness of the nanotube layer. The post-treatment is performed with the plasma at the same substrate temperature. For the post-treatment, the hydrogen containing gas is used as a plasma source gas. During the transition from the nanotube growth step to the post-treatment step, the pressure in the plasma process chamber is stabilized with the aforementioned purifying gas without shutting off the plasma in the chamber. This eliminates the need to purge and evacuate the plasma process chamber.

摘要： A crucible, which has first member and second cylindrical body, is disposed in a lower chamber. A pedestal is disposed inside the first member, and a seed crystal is fixed to the pedestal. A second heat insulator is provided between an inlet conduit and a crucible. A first heat insulator is provided at a halfway portion of the inlet conduit. With these heat insulators, a temperature gradient occurs in the inlet conduit at a portion thereof that is closer to the crucible. A mixture gas is introduced into the crucible. The mixture gas is heated up gradually when passing through the inlet conduit and is introduced into the crucible to form SiC single crystals in high quality.

摘要： In a plasma processing apparatus according to the present invention, a gas inlet port and a discharge port are provided on a chamber for introducing and discharging gas into and from the chamber respectively. A sample to be etched is placed on an electrode part, so that a high-frequency power source applies a high-frequency bias to the sample. An electromagnet provided on the periphery of a plasma generation area generates a magnetic field while a waveguide connected to an upper potion of the chamber introduces a microwave into the plasma generation area through a microwave introduction window. Electron cyclotron resonance is excited for the gas for generating plasma. At least a surface of the microwave introduction window exposed to the plasma generation area is made of quartz, while the gas contains fluorine. The apparatus having the aforementioned structure can remove a material adhering to the surface of the microwave introduction window when the sample is etched.

摘要： This invention relates to process sequence by atomic layer chemical vapor processing that includes thin film deposition for diffusion barriers in the vias, trenches or contact plug-holes followed by gap fill with ALD/CVD process and subsequent removal of the blanket film on the top by Atomic Layer Processing/Chemical Vapor Processing. The processes can be carried out in separate chambers or may be combined into one or more chambers. The apparatus employed in these processing steps allows the practitioner to rapidly complete process sequences of barrier deposition, gap fill and top layer planarization. In case of copper metallization scheme, ALD gap fill can be employed to replace electrochemical deposition of copper. Atomic layer removal of copper and other blanket films by gas phase reactions can replace the chemical-mechanical-polishing of the blanket films. Additional advantages of such processing scheme are elimination of defects, dishing, erosion, corrosion, liquid-electrolyte, slurry and other liquid waste. Benefit of such a process scheme is entrapment of the effluents and also precise metering and control of the injected amount to affect the chemical reaction in each step of the sequence that can lead to significant savings and higher chemical utilization efficiency.

摘要： A method is disclosed for producing high quality semi-insulating silicon carbide crystals in the absence of relevant amounts of deep level trapping elements. The invention includes the steps of heating a silicon carbide crystal having a first concentration of point defect related deep level states to a temperature above the temperatures required for CVD growth of silicon carbide from source gases, but less than the sublimation temperature of silicon carbide under the ambient conditions to thereby thermodynamically increase the number of point defects and resulting states in the crystal, and then cooling the heated crystal to approach room temperature at a sufficiently rapid rate to maintain a concentration of point defects in the cooled crystal that remains greater than the first concentration.

摘要： A method for growing a single crystal GaN film at least 2 microns thick on a Si substrate is disclosed. The method includes growing a prelayer, a buffer layer including AlN on the Si substrate and a plurality of GaN layers and AlN layers deposited alternatively on the top of the AlN buffer layer. By controlling the deposition conditions and timings of the plurality of GaN layers and AlN layers, the single crystal GaN film can be grown thicker than 2 microns without cracks or pits.

摘要： A silicon annealed wafer having a sufficient thick layer free from COP defects on the surface, and a sufficient uniform BMD density in the inside can be produced by annealing either a base material wafer having nitrogen at a concentration of less than 1null1014 atoms/cm3, COP defects having a size of 0.1 nullm or less in the highest frequency of occurrence and no COP defects having a size of 0.2 nullm or more, oxygen precipitates at a density of 1null104 counts/cm2 or more, and BMDs (oxygen precipitates), where the ratio of the maximum to the minimum of the BMD density in the radial direction of the wafer is 3 or less, or a base material wafer grown at specific average temperature gradients within specific temperature ranges and specific cooling times for a single crystal at a nitrogen concentration of less than 1null1014 atoms/cm3, employing the Czochralski method. Moreover, a silicon epitaxial wafer having very small defects and a uniform BMD distribution in the inside can be formed by growing an epitaxial layer on the surface of either the first type base material wafer or the second type base material wafer. Both the silicon annealed wafer and the silicon epitaxial wafer greatly reduce the rate of producing defective devices, thereby enabling the device productivity to be enhanced.

摘要： An improved method for controlling nucleation sites during superabrasive particle synthesis can provide high quality industrial superabrasive particles with high yield and a narrow size distribution. The synthesis method can include forming a raw material layer, forming a particulate catalyst layer adjacent the raw material layer, and placing crystalline seeds in a predetermined pattern at least partially in the catalyst layer or raw material layer to form a growth precursor. Alternatively, the raw material and catalyst material can be mixed to form a particulate crystal growth layer and then placing the crystalline seeds in a predetermined pattern in the growth layer. Preferably, seeds can be substantially surrounded by catalyst material. The growth precursor can be maintained at a temperature and pressure at which the superabrasive crystal is thermodynamically stable for a time sufficient for a desired degree of growth. The crystalline seeds can be placed in a predetermined pattern using a template, a transfer sheet, vacuum chuck or similar techniques. The superabrasive particles grown using the described methods typically have a high yield of high quality industrial particles and a narrow distribution of particle sizes.
