    摘要: An optical waveguide device for coupling an external wave with a guided wave by means of a grating coupler formed on an optical waveguide device which lies on a substrate. The grating coupler is further coated with a cladding layer. An external wave is transformed into a guided wave after being diffracted by a first grating coupler, and travels along the waveguide to a second grating coupler. The guided wave is then subjected to diffraction by means of the second grating coupler, whereupon a minus first-order wave is diffracted only toward the substrate, whilst other waves of higher order are respectively diffracted toward the cladding layer and the substrate. The wave diffracted toward the cladding layer is totally reflected from a cladding layer boundary furtherst from the substrate, thereby passing through the substrate. The diffracted wave thus reflected interferes with the other wave of the same order diffracted to the substrate, thereby weakening each other.

The main wiring layer contains an added element to prevent migration. The adjacent conductor layer is formed of a material for preventing a main constituent element and the added element of the main wiring layer from diffusing into the substrate beneath the adjacent conductor layer, and the concentration of the added element at a location close to an interface between the adjacent conductor layer and the main wiring layer is low compared to the concentration of the added element in the main wiring layer spaced from the adjacent conductor layer.

    摘要: Diffusion layers 2–5 are formed on a silicon substrate 1, and gate dielectric films 6, 7 and gate electrodes 8, 9 are formed on these diffusion layers 2–5 so as to be MOS transistors. Zirconium oxide or hafnium oxide is used as a major component of gate dielectric films 6, 7. Gate dielectric films 6, 7 are formed, for example, by CVD. As substrate 1, there is used one of which the surface is (111) crystal face so as to prevent diffusion of oxygen into silicon substrate 1 or gate electrodes 8, 9. In case of using a substrate of which the surface is (111) crystal face, diffusion coefficient of oxygen is less than 1/100 of the case in which a silicon substrate of which the surface is (001) crystal face is used, and oxygen diffusion is controlled. Thus, oxygen diffusion is controlled, generation of leakage current is prevented and properties are improved. There is realized a semiconductor device having high reliability and capable of preventing deterioration of characteristics concomitant to miniaturization.

    摘要: A semiconductor device free from electric failure in transistors at upper trench edges can be produced by a simplified process comprising basic steps of forming a pad oxide film on the circuit-forming side of a semiconductor substrate; forming an oxidation prevention film on the pad oxide film; removing the oxidation presention film and the pad oxide film at a desired position, thereby exposing the surface of the semiconductor substrate; horizontally recessing the pad oxide film, etching the exposed surface of the semiconductor substrate by isotropic etching; forming a trench to a desired depth, using the oxidation prevention film as a mask; horizontally recessing the pad oxide film; oxidizing the trench formed in the semiconductor substrate; embedding an embedding isolation film in the oxidized trench; removing the embedding isolation film formed on the oxidation prevention film; removing the oxidation prevention film formed on the circuit-forming side of the semiconductor substrate; and removing the pad oxide film formed on the circuit-forming side of the semiconductor substrate, where round upper trench edges with a curvature can be obtained, if necessary, by conducting isotropic etching of exposed surface of the semiconductor substrate and horizontally recessing of the pad oxide film before the oxidation of the trench, whereby only one oxidation step is required.
