    摘要: An alignment mark for use in electron beam lithography for manufacturing a fine semiconductor structure by repeating a regrowth of a compound semiconductor layer and a fine process including electron beam exposure. The alignment mark includes a lower protection layer made of tungsten formed on a compound semiconductor substrate, a mark main body made of gold, chromium or platinum shaped into a desired pattern having a sharp edge profile which generates a detection signal of a mark position having a large gain, and an upper protection layer covering the mark main body and made of silicon oxide which does not react significantly with substances constituting a compound semiconductor layer. The mark main body has a thickness which is not less than 100 nm.

    摘要: The total base-collector capacitance of a double-heterostructure bipolar transistor device is reduced by removing semiconductor material from the extrinsic regions and replacing the removed material with a relatively-low-dielectric-constant material, The base-collector capacitance is further reduced by using a composite subcollector structure that permits the extrinsic regions to be made thicker than the intrinsic region of the device.

    摘要: The lateral base resistance of a DHBT device is reduced and its high-speed operating characteristics thereby improved by forming a structure that initially includes a relatively thick extrinsic base layer overlying a relatively thin intrinsic base layer. The extrinsic base layer is then etched to form a window in which an emitter layer is deposited. In that way, the growth time for formation of the base-emitter junction is minimized. High-performance devices are thereby realized in a relatively simple process that has advantageous self-alignment features.

    摘要: The present invention can precisely manufacture an X-ray mask pattern at intervals of less than 10 nm by using a thin film crystalline growth method, applying a laminated layer body of a fine structure having a precision of less than 1 atomic layer onto a substrate, and utilizing the difference in X-ray absorption coefficients. A method of manufacturing an X-ray exposure mask comprises the steps of alternately laminating two kinds of material consisting of a combination of a semiconductor, metal and insulator having substantially equal lattice constants and largely different coefficients of X-ray absorption on a substrate of a crystal body to thicknesses of less than 10 .ANG. by an epitaxial crystal growth method, and manufacturing a mask for exposing streak-like X-rays on a desired resist as a result of the largely different coefficients of X-ray absorption between each layer.

    摘要: The present invention relates to a method of manufacturing an exposure mask having an unprecedented supermicrostructure for an X-ray exposure method favorable for conventional supermicro exposure using lithography techniques. The method of manufacturing an X-ray exposure mask comprises the steps of alternately laminating two kinds of compound semiconductors as a thin film having a periodic structure with controllability of about one atomic layer on a substrate selectively etching only one material for forming the periodic structure, forming an uneven difference between adjacent layers of the laminate body, and manufacturing a mask for exposing streaks on a desired resist with the aid of a difference of X-rays absorption amounts between each layer by exposing X-ray in parallel to the direction of the laminate layer.

    摘要: An apparatus for performing a plasma-etching of a LSI device including a Cu interconnection, a low-k film, and a diffusion prevention film has a treatment chamber, into which an etching gas is introduced, and a support table which is equipped with electrodes and on which said LSI device is placed. In this apparatus, the etching gasses are turned into plasma by supplying radio frequency power to electrodes provided within the treatment chamber, so that the LSI device is etched with ions of the plasma. In this apparatus, a sulfur-containing gas and a fluorine-containing gas are mixed to the etching gasses, so that the diffusion prevention film is selectively etched against the low-k film.
