    摘要: Disclosed is a method of manufacturing semiconductor devices, in which a monocrystalline thin film is formed by dissolving and recrystallizing either amorphous or poly- . crystalline thin film by annealing with energy beams, comprising the steps of: forming a compound film of a belt-shaped high melting point metal having a width narrower than the diameter of said energy beams and polycrystalline silicon, on said amorphous or polycrystalline thin film; causing said amorphous or polycrystalline thin film to contact with a monocrystalline substrate beneath the center line of said belt-shaped compound film at a position of more than 50 to 200 µm remote from the end of the belt-shaped compound film in the scanning direction of said energy beams, with the contact shape being a tiny spot narrower than the width of the belt-shaped compound film; radiating said energy beams, penetrating through said belt-shaped compound film to scan parallel to the belt, starting from the vicinity of the end of the belt-shaped compound film, and inducing crystal growth of the amorphous or polycrystalline thin film beneath the belt-shaped compound film, starting from the monocrystals inheriting the crystalline configuration of the monocrystalline substrate developed by epitaxial growth from the monocrystalline substrate in the amorphous or polycrystalline thin film contacting with the monocrystalline substrate near the end of the belt-shaped compound film.
    It is more preferable to compose so that the upper surface of the amorphous or polycrystalline thin film contacting with the monocrystalline substrate may be flush with the upper surface of the armophous or polycrystalline thin film not contacting with the monocrystalline substrate near this contacting portion.

    摘要: It is described an improved process of RIE plasma attack of the layer of dielectric material on the surface of wafers of semiconductor material, in correspondence of areas purposely defined by masking, for exposing the underlying semiconductor crystal, in preparation to depositing a layer of material of metallic conduction. After having provided to remove a certain thickness of dielectric according to the known technique, the conditions of attack are modified, substituting the plasma gases and reducing the "bias" and attack is resumed of the residual layer of dielectric and preferably also of a certain thickness of the semiconductor crystal in the same reactor. Ohmic contacts with relatively low contact resistance and great reliability are obtained with a minimum handling of the wafers.

    摘要: In a system for continuously exposing desired patterns and their backgrounds on the surface of a target (20), a first electron beam emitted from a first electron gun (10) is converged by condenser lenses (12, 14, 16) and an objective lens (18) to be focused on the surface of the target (20). A second electron beam emitted from a second electron gun (32) is defocused at the target (20) surface by a condenser lens (34) and a deflecting coil (36). A deflector (22) selects the first or second electron beams. While the target (20) surface is being scanned with the selected electron beam, the beam is deflected by a scanning deflector (30). In delineating a pattern, the target (20) surface is scanned with the first electron beam. In delineating a background, on the other hand, the target (20) surface is scanned with the second electron beam.

    摘要: The preferred embodiment discloses a new method of manufacturing semiconductor devices, in which monocrystalline thin film is formed by dissolving and recrystallizing either amorphous or polycrystalline thin film (6) via annealing means by radiation of energy beams (9), wherein the manufacturing method comprises: the formation of a belt-shaped high melting point metal film (8) having a width narrower than the diameter of the energy beams on either amorphous or polycrystalline thin film; beam scanning in parallel with the said belt by means of radiating energy beams onto the said belt-shaped high melting point metal film; and generation of a nucleus in a limited area beneath the belt-shaped thin film at the moment the film-covered amorphous or polycrystalline area dissolves and recrystallizes so that the said recrystallized area can eventually grow into a moncrystalline configuration.
