    摘要: An at least unilaterally open hollow body of silicon or other semiconductor material is produced by thermally reducing a gaseous compound of the same material and precipitating the segregated material upon a heated carrier of different material, preferably graphite or other industrial carbon, and thereafter removing the resulting hollow semiconductor body from the carrier. The gaseous compound is supplied to the heated carrier in mixture with a reduction gas, preferably hydrogen, in a molar ratio that substantially corresponds to the reaction equilibrium at the carrier temperature obtaining at the beginning of the reduction and precipitation process. After the precipitated hollow body has reached a layer thickness of a few microns, the molar ratio is changed so as to increase the rate of precipitation. The method can be modified by changing the throughput of the gaseous mixtures from a lower to a higher value after a layer thickness of a few microns has been reached and then continuing the precipitation at a higher rate until the desired full layer thickness is obtained.

    摘要: In an infrared lamp instead of a glass or quartz bulb, a tube sealed at one end and consisting of pyrolytically precipitated, polycrystalline silicon is used. It is gas-tight even at a wall thickness of 0.5 mm and mechanically stable even at elevated temperatures, up to 1,300* C. Silicon possesses a distinct filter effect and is permeable only to beams with a wave length greater than 1.1 Mu .

    摘要: A method creates structured cavities with submicrometer dimensions in a cavity layer of a semiconductor device. A processing material that incorporates a swelling agent is deposited on ridges of a working layer that is constructed of ridges and trenches. The processing material expands over the trenches during swelling; and covered cavities thus emerge from the trenches.

    摘要: This invention deals with the formation of the multi-level electrode metal structure and the interconnecting inter-level metal studs used in the fabrication of VLSI circuits. After the metal layers have been formed the inter-level dielectric material used in forming the structure is etched away leaving an air dielectric between the levels. The electrode metal and the inter-level metal studs are coated with a thin envelope oxide and the entire structure is covered with a passivation layer using material with a poor step coverage. The structure of this invention provides reduced parasitic capacitance, better step coverage in interconnecting layers, and improved circuit performance.

    摘要: A new method of trench isolation incorporating thermal stress releasing voids is described. Two sets of narrow trenches are etched into the silicon substrate not covered by a photoresist mask wherein the second set of trenches alternate with the first set of trenches. The first set of trenches is filled with an insulating layer. A second insulating layer is deposited over the surface of the substrate and within the second set of trenches wherein said insulating layer has step coverage such that voids are formed and are completely enclosed within the second set of trenches completing the thermal stress releasing device isolation of the integrated circuit. The method of forming thermal stress released polysilicon gate spacers in an integrated circuit is described. Polysilicon gate electrodes are formed on the surface of the semiconductor substrate. Sucessive sidewalls are formed on the gate electrodes of thin silicon dioxide, silicon nitride, and silicon dioxide. The silicon nitride spacers are removed leaving trenches between the thin silicon dioxide sidewalls and the silicon dioxide spacers. A thin insulating material is deposited over the surface of the gate electrodes and the sidewalls with a step coverage such that the trenches between the thin oxidation and the silicon dioxide spacers are not filled by the thin insulating layer but are covered by the thin insulating layer leaving voids which complete the thermal stress released polysilicon gate spacer formation in the fabrication of an integrated circuit.

    摘要: A metal connection for an integrated circuit device is effectively "cast" in place at any level of an integrated circuit. The "mold" for the connection is formed by depositing and patterning a sacrificial material, such as aluminum oxide or other metal oxides, and covering the sacrificial material with a protective material such as silicon dioxide or other insulators. After forming bore holes to the deposit of sacrificial material through the protective layer, the sacrificial material is removed by isotropic etching to form a cavity beneath and at least partially overlaid by the protective layer. Alternatively, a defect may be produced below the protective layer and filled with metal either with or without enlargement by further removal of material. This cavity is then filled with metal by deposition of the metal by, for instance, evaporation, sputtering and chemical vapor deposition or combinations thereof. Connections formed by this technique can be produced at any level of the integrated circuit and do not interfere with surface wiring. A plurality of such connections may be simultaneously formed at the same or different levels of the integrated circuit and the method may be repeated to form multi-level wiring patterns.
