  • Patent number: 8835880
    Abstract: A cluster source is used to assist charged particle beam processing. For example, a protective layer is applied using a cluster source and a precursor gas. The large mass of the cluster and the low energy per atom or molecule in the cluster restricts damage to within a few nanometers of the surface. Fullerenes or clusters of fullerenes, bismuth, gold or Xe can be used with a precursor gas to deposit material onto a surface, or can be used with an etchant gas to etch the surface. Clusters can also be used to deposit material directly onto the surface to form a protective layer for charged particle beam processing or to provide energy to activate an etchant gas.

  • Patent number: 8617668
    Abstract: A method of depositing a material on a work piece surface. The method comprising providing a deposition precursor gas at the work piece surface; providing a purification compound including a nitrogen-containing compound at the work piece surface; and directing a beam toward a local region on the work piece surface, the beam causing decomposition of the precursor gas to fabricate a deposit on the work piece surface, the deposited material including a contaminant, the purification compound causing a reduction in the concentration of the contaminant and providing a deposited material that includes less contamination than a material deposited using the same methodology but without using a purification compound.

  • Publication number: 20110070381
    Abstract: A system for beam-induced deposition or etching, in which a charged particle or laser beam can be directed to a work piece within a single vacuum chamber, either normally incident or at an angle. Simultaneously with beam illumination of the work piece, a deposition or etch precursor gas is co-injected or premixed with a purification compound and (optionally) a carrier gas prior to injection into the process chamber. The beam decomposes the deposition precursor gas to deposit a film only in areas illuminated by the beam, or decomposes the etch precursor gas to etch a film only in areas illuminated by the beam. Undesired impurities such as carbon in the deposited film are removed during film growth by interaction with adsorbed species on the work piece surface that are generated by interaction of the beam with adsorbed molecules of the film purification compound. Alternatively, the film purification compound can be used to inhibit oxidation of the material etched by the etch precursor gas.

  • Patent number: 7621976
    Abstract: Provided are silver-containing powders and a method and apparatus for manufacturing the silver-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications.

  • Publication number: 20060045987
    Abstract: A method of localized plasma processing improves processing speed and reduces work piece damage compared to charged particle beam deposition and etching. In one embodiment, a plasma jet exits a plasma generating chamber and activates a reactive gas. A jet of plasma and reactive gas impacts and processes the work piece. Because the plasma and the ions in the reactive gas can have low kinetic energy, there can be little or no surface damage. This is particularly useful for deposition processes. When it is desired to etch material, the reactive ions can be more energetic to enhance etching.
