METHOD OF FORMING SEMICONDUCTOR DEVICE HAVING CARBON NANOTUBE
In a method, a charged metal dot is deposited on a first position of a surface of a semiconductor substrate. Then, a charged region is formed on a second position of the surface of the semiconductor substrate, thereby establishing of which an electric field direction from the first position toward the second position. The first position is spaced apart from the second position by a distance. Thereafter, a precursor gas flows along the electric field direction on the semiconductor substrate, thereby forming a carbon nanotube (CNT) on the semiconductor substrate.
THIN FILM LAMINATE, THIN FILM DEVICE AND MULTILAYER SUBSTRATE
A thin film laminate comprises a metal layer consisting of a metal, and a thin film laminated on the surface of the metal layer, wherein a first direction is defined as one direction parallel to the surface of the metal layer, and a second direction is defined as one direction parallel to the surface of the metal layer and crossing the first direction; and the metal layer contains a plurality of first metal grains consisting of the metal and extending in the first direction on the surface of the metal layer, and a plurality of second metal grains consisting of the metal and extending in the second direction on the surface of the metal layer.
NANOFABRICATION USING A NEW CLASS OF ELECTRON BEAM INDUCED SURFACE PROCESSING TECHNIQUES
Methods and systems for direct lithographic pattern definition based upon electron beam induced alteration of the surface chemistry of a substrate are described. The methods involve an initial chemical treatment for global definition of a specified surface chemistry (SC). Electron beam induced surface reactions between a gaseous precursor and the surface are then used to locally alter the SC. High resolution patterning of stable, specified surface chemistries upon a substrate can thus be achieved. The defined patterns can then be utilized for selective material deposition via methods which exploit the specificity of certain SC combinations or by differences in surface energy. It is possible to perform all steps in-situ without breaking vacuum.
Method and apparatus for fabricating fibers and microstructures from disparate molar mass precursors
The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures. In some embodiments, the invention also relates to the fabrication of certain functionally-shaped fibers and microstructures. In some embodiments, the invention may also utilize laser beam profiling to enhance fiber and microstructure fabrication.

Method of burying sample trench
The invention provides a method of burying trenches of a sample comprises at least the steps of: from the sample having the trenches extending from one surface into a depth direction, cutting a sample piece of a small part including the trenches; and by irradiating an electron beam toward the inside of the trenches from a side surface extending along the depth direction of the sample piece and simultaneously injecting a compound gas into the inside of the trenches from openings on the side of the one surface of the trench, decomposing the compound gas with secondary electrons generated by irradiation of the electron beam and depositing constituents of the compound gas within the trenches. Therefore, the method can bury the trenches uniformly without generating cavities within the trenches even if the trenches of the sample piece have a high aspect ratio deep in a depth direction.
Patterned atomic layer etching and deposition using miniature-column charged particle beam arrays
Methods and systems for direct atomic layer etching and deposition on or in a substrate using charged particle beams. Electrostatically-deflected charged particle beam columns can be targeted in direct dependence on the design layout database to perform atomic layer etch and atomic layer deposition, expressing pattern with selected 3D-structure. Reducing the number of process steps in patterned atomic layer etch and deposition reduces manufacturing cycle time and increases yield by lowering the probability of defect introduction. Local gas and photon injectors and detectors are local to corresponding columns, and support superior, highly-configurable process execution and control.
SILICON COMPOUNDS AND METHODS FOR DEPOSITING FILMS USING SAME
A composition, and chemical vapor deposition method, is provided for producing a dielectric film. A gaseous reagent including the composition is introduced into the reaction chamber in which a substrate is provided. The gaseous reagent includes a silicon precursor that includes a silicon compound according to Formula I as defined herein. Energy is applied to the gaseous reagents in the reaction chamber to induce reaction of the gaseous reagents and to thereby deposit a film on the substrate. The film as deposited is suitable for its intended use without an optional additional cure step applied to the as-deposited film. A method for making the composition is also disclosed.
Deposition or treatment of diamond-like carbon in a plasma reactor
A method of performing deposition of diamond-like carbon on a workpiece in a chamber includes supporting the workpiece in the chamber facing an upper electrode suspended from a ceiling of the chamber, introducing a hydrocarbon gas into the chamber, and applying first RF power at a first frequency to the upper electrode that generates a plasma in the chamber and produces a deposition of diamond-like carbon on the workpiece. Applying the RF power generates an electron beam from the upper electrode toward the workpiece to enhance ionization of the hydrocarbon gas.
