    摘要: A waveguide type reduction type image sensor has a waveguide type light source having a light emitting element and a substrate including optical waveguides having a planar waveguide and a tapered waveguide. The waveguide type reduction type image sensor also has a light detecting section having a microlens array, an optical waveguide substrate and a CCD array. The microlens array converges reflected light from an original onto the incident face of the optical waveguide substrate. The optical waveguide substrate has L-shaped optical waveguides for guiding the converged light to the CCD array located on a substrate face perpendicular to the incident face. The CCD array converts the guided light to an electric signal and outputs this electric signal. A manufacturing method of this waveguide type reduction type image sensor is also shown.

    摘要: A method for manufacturing a semiconductor wafer includes a carbon layer formation step, a through hole formation step, a feed layer formation step, and an epitaxial layer formation step. In the carbon layer formation step, a carbon layer (71) is formed on a surface of a substrate (70) made of polycrystalline SiC. In the through hole formation step, through holes (71c) are formed in the carbon layer (71) formed on the substrate (70). In the feed layer formation step, a Si layer (72) and a 3C—SiC polycrystalline layer (73) are formed on a surface of the carbon layer (71). In the epitaxial layer formation step, the substrate (70) is heated so that a seed crystal made of 4H—SiC single crystal is formed on portions of the surface of the substrate (70) that are exposed through the through holes (71c), and a close-spaced liquid-phase epitaxial growth of the seed crystal is caused to form a 4H—SiC single crystal layer.
