  • Publication number: 20090316268
    Abstract: Methods for producing a quartz glass component with reflector layer are known in which a reflector layer composed of quartz glass acting as a diffuse reflector is produced on at least part of the surface of a substrate body composed of quartz glass. In order, taking this as a departure point, to specify a method which enables cost-effective and reproducible production of uniform SiO2 reflector layers on quartz glass components, it is proposed according to the invention that the reflector layer is produced by thermal spraying by means of SiO2 particles being fed to an energy carrier, being incipiently melted or melted by means of said energy carrier and being deposited on the substrate body. In the case of a quartz glass component obtained according to the method, the SiO2 reflector layer is formed as a layer which is produced by thermal spraying and has an opaque effect and which is distinguished by freedom from cracks and uniformity.

  • Patent number: 7338699
    Abstract: In film-forming devices and plasma-processing devices, filmy matter adheres to the surfaces of the inner parts and it peels to cause dust and particles in the devices. In the devices, the dust and particles contaminate the objects for film formation thereon or the objects to be processed with plasma. For preventing the objects from being contaminated with them, the inner parts of the devices must be frequently exchanged every time when they have received any minor filmy matter thereon, and this lowers the productivity in the devices. When a modified glass part of which the surface is modified with spherical or bell-like island projections having a width and a height of from a few ?m to a few hundreds ?m is used in a film-forming device and in a plasma-processing device, then its ability to hold the filmy substance having adhered thereto is good and its resistance to plasma is also good.

In some embodiments high purity gaseous and/or liquid intermediate compounds of silicon (or silicon germanium) are converted directly to polycrystalline films by a thermal plasma chemical vapor deposition process or by a thermal plasma spraying technique. The intermediate compounds of silicon (or silicon germanium) are injected into the thermal plasma source where temperatures range from 2000 K to about 20,000 K. The compounds dissociate and silicon (or silicon germanium) is deposited onto substrates. Polycrystalline films having densities approaching the bulk value are obtained on cooling. PN junction photovoltaic cells can be directly prepared by spraying, or doped films after heat treatment are subsequently transformed to viable photovoltaic cells having high efficiency, low cost at a high throughput.

    Abstract: A method is provided for forming a Si and Si—Ge thin films. The method comprises: providing a low temperature substrate material of plastic or glass; supplying an atmosphere; performing a high-density (HD) plasma process, such as an HD PECVD process using an inductively coupled plasma (ICP) source; maintaining a substrate temperature of 400 degrees C., or less; and, forming a semiconductor layer overlying the substrate that is made from Si or Si-germanium. The HD PECVD process is capable of depositing Si at a rate of greater than 100 ? per minute. The substrate temperature can be as low as 50 degrees C. Microcrystalline Si, a-Si, or a polycrystalline Si layer can be formed over the substrate. Further, the deposited Si can be either intrinsic or doped. Typically, the supplied atmosphere includes Si and H. For example, an atmosphere can be supplied including SiH4 and H2, or comprising H2 and Silane with H2/Silane ratio in the range of 0–100.

  • Patent number: 7101591
    Abstract: This invention provides a process for producing an organic polymer film whereby when using it as an interlayer insulating film in a semiconductor device, the film exhibits higher adhesiveness at its interfaces where other semiconductor materials are in contact with the lower and the upper surface of the film while an effective dielectric constant in the whole organic polymer film can be further reduced. Specifically, a plurality of organic monomers vaporized is sprayed onto a heated substrate surface via plasma generated in a reaction chamber to form a copolymer film comprising frame composed of a plurality of organic monomer units.

  • Patent number: 7026009
    Abstract: A component for a substrate processing chamber comprises a structure having a textured coating with surface grains. The component is evaluated by directing a beam of electrons onto the textured coating of the component to cause at least some of the electrons to be backscattered. The backscattered electrons are detected and a signal image is generated. The component is selected when the signal image exhibits surface grains sized from about 0.1 to about 5 micron. In one version, the component is also selected when the grains are substantially flower shaped.

  • Patent number: 6896933
    Abstract: A method of maintaining a non-obstructed interior opening in a kinetic spray nozzle is disclosed. The method includes the steps of providing a mixture of particles including first particle population and a second particle population; entraining the mixture of particles into a flow of a gas at a temperature below the melt temperature of the particle populations; and directing the mixture of particles entrained in the flow of gas through a supersonic nozzle to accelerate the first particle population to a velocity sufficient to result in adherence of the first particle population on a substrate positioned opposite the nozzle. The operating conditions of the kinetic spray system are selected such that the second particle population is not accelerated to a velocity sufficient to result in adherence when it impacts the substrate.
