    摘要: Method for etching a substrate wherein, after placing in an etching chamber, said substrate is treated with a mixture of HF and acetic acid. Acetic acid is introduced into the chamber first, followed by the hydrogen fluoride. Hydrogen fluoride is introduced via an intermediate stage during which the hydrogen fluoride is stored in an auxiliary chamber. By this means back-flow of a corrosive mixture consisting of hydrogen fluoride and acetic acid into the piping assembly for hydrogen fluoride is prevented and, thus, the life of the piping assembly concerned is appreciably prolonged and metal contamination on substrate treated later is prevented.

    摘要: A glass or metal wire is precisely etched to form the paraboloidal or ellipsoidal shape of the final desired capillary optic. This shape is created by carefully controlling the withdrawal speed of the wire from an etchant bath. In the case of a complete ellipsoidal capillary, the etching operation is performed twice in opposite directions on adjacent wire segments. The etched wire undergoes a subsequent operation to create an extremely smooth surface. This surface is coated with a layer of material which is selected to maximize the reflectivity of the radiation. This reflective surface may be a single layer for wideband reflectivity, or a multilayer coating for optimizing the reflectivity in a narrower wavelength interval. The coated wire is built up with a reinforcing layer, typically by a plating operation. The initial wire is removed by either an etching procedure or mechanical force. Prior to removing the wire, the capillary is typically bonded to a support substrate. One option for attaching the wire to the substrate produces a monolithic structure by essentially burying it under a layer of plating which covers both the wire and the substrate. The capillary optic is used for efficiently collecting and redirecting the divergent radiation from a source which could be the anode of an x-ray tube, a plasma source, the fluorescent radiation from an electron microprobe, or some other source of radiation.

    摘要: A method for producing stable atmospheric pressure glow discharge plasmas using RF excitation and the use of said plasmas for modifying the surface layer of materials. The plasma generated by this process and its surface modification capability depend on the type of gases used and their chemical reactivity. These plasmas can be used for a variety of applications, including etching of organic material from the surface layer of inorganic substrates, as an environmentally benign alternative to industrial cleaning operations which currently employ solvents and degreasers, as a method of stripping paint from surfaces, for the surface modification of composites prior to adhesive bonding operations, for use as a localized etcher of electronic boards and assemblies and in microelectronic fabrication, and for the sterilization of tools used in medical applications.

    摘要: An optical fiber made up of a core for propagating the light and a clad covering the core for confining the light propagated in the core. The optical fiber has a tapering protrusion at the apex for entrance and exiting of light. The optical fiber is used in a photon scanning tunneling microscope detecting the evanescent light localized in an area smaller in size than the wavelength of light on the surface of an sample as an optical probe disposed in proximity to the surface of the sample for scattering the evanescent light for detecting the scattered light. The optical fiber is optically coupled to an optical waveguide for constituting an optically coupled element. With this optically coupled element, a protrusion of the optical fiber operates as a collection unit for collecting the light propagated in the core. The light collected by the protrusion enters the optical waveguide.

    摘要: A method and system for forming microlens (78) on an optical fiber (60) include optical fiber lensing device (10) having lowering mechanism (18) for inserting optical fiber (60) at a predetermined and controlled speed to a predetermined depth in oil-acid bath having oil layer (62), acid layer (64), and boundary (68) between oil layer (62) and acid layer (64). The next step is to etch optical fiber (60) at boundary (68) by forming meniscus (66) around optical fiber (60) to selectively and controllably form on optical fiber (60) a microlens (78) having a predetermined shape, preferably a hyperbolic shape. The etching includes the steps of first tapering optical fiber (60) to a shape determined by the distance that optical fiber (60) is first inserted into acid layer (64). The etch step further chemically mills microlens (78) on optical fiber (60) to the predetermined shape by controlling the etch time and position of optical fiber (60) relative to boundary (68) for etching optical fiber (60) at boundary (68).

    摘要: A method of forming sub-lithographic elements and spaces therebetween where the pitch may be reduced with continuously adjustable line and space dimensions, and a structure resulting from the method, are disclosed. A plurality of spaced convertible members are formed on a substrate. A portion of each member is then converted, thereby reducing the dimensions of the unconverted portion of the member while increasing the width of the member plus its converted layer. A conformal layer of material is then deposited over the converted members, followed by directional etching of the conformal layer. The unconverted portion of the member is then removed. The line and space dimensions can be continuously adjusted by altering either or both of the member's converted layer and conformal layer.

    摘要: A metal or glass wire is etched with great precision into a very narrowly tapering cone which has the shape of the desired final capillary-optics bore. By controlling the rate of removal of the wire from an etchant bath, a carefully controlled taper is produced. A sensor measures the diameter of the wire as it leaves the surface of the etchant. This signal is used for feedback control of the withdrawal speed. The etched wire undergoes a treatment to produce an extremely low surface-roughness. The etched and smoothed wire is coated with the material of choice for optimizing the reflectivity of the radiation being focused. This could be a vacuum evaporation, sputtering, CVD or aqueous chemical process. The coated wire is either electroplated, built up with electroless plating, or encapsulated in a polymer cylinder such as epoxy to increase the diameter of the wire for easier handling and greater robustness. During this process, the wire is vertically oriented and tensioned to assure that the wire is absolutely straight. The coated and electroformed wire is bonded to a flat, rigid substrate and is then periodically segmented by cutting or etching a series of narrow slits or grooves into the wire. The wire is vertically oriented and tensioned during the bonding process to assure that it is straight. The original wire material is then chemically etched away through the slits or otherwise withdrawn to leave the hollow internal bore of the final tapered-capillary optical element.
