Abstract
PURPOSE:To obtain an IC, the degree of integration thereof is high and which functions at high speed, by forming an electrode wiring layer in the multilayer constitution of poly Si and Al and doping the impurity of the same conduction type as the diffusion layer of a substrate to the connecting section of the diffusion layer of a substrate to the connecting section of the diffusion layer and poly Si. CONSTITUTION:An opening is forned to a SiO2 film 12 on an N type Si substrate 11 and a P layer 13 is shaped, and the wiring layers of poly Si 14 and Al 15 are formed. The P type impurity is diffused from the whole surface of diffused to poly Si from the P layer 13 in the opening section in the poly Si 14, and both the poly Si 14 and the P layer 13 are kept in the same conduction type. According to this constitution, even when the opening of the film 12 protrudes from the layer 13, the layer 13 can small be shaped because the direct alloying and short circuit of the upper Al wiring 15 with the Si substrate 11 can be avoided by the presence of the P type poly Si layer. Contact resistance does not increase in the contact of wiring and the layer 13 because both the wiring and the layer 13 are made of Si, both may be connected in minute size, and the IC, the degree of integration thereof is high and which functions at high speed, is obtained.
