Abstract
A semiconductor integrated circuit device which comprises a substrate, a first continuous longitudinal diffusion layer formed in the substrate and a second continuous longitudinal diffusion layer constitutes source areas of a plurality of MOS transistors. The second diffusion layer constitutes drain areas of the transistors. The device further comprises a first polycide layer formed on and along each of the first and second diffusion layers in contact therewith and a second polycide layer for constituting a gate electrode of each of the transistors. The second polycide layer is formed on and transversing the first polycide layers in a direction perpendicular to the first and second diffusion layers. An insulation layer is interposed between the first and second polycide layers.
