Abstract:
A method for manufacturing a semiconductor integrated circuit device comprising:forming a first oxide film on a top surface of a semiconductor substrate; forming a first electrode, having a first sidewall and a second sidewall, on the first oxide film; forming a second electrode on the first oxide film, wherein the second electrode has a first sidewall and a second sidewall, and wherein the first sidewall of the second electrode faces the second sidewall of the first electrode; forming a first diffusion region within the substrate in an area adjacent to the first sidewall of the first electrode; forming a second diffusion region within the substrate in an area between the second sidewall of the first electrode and the first sidewall of the second electrode; forming a third diffusion region within the substrate in an area adjacent to the second sidewall of the second electrode; forming a first silicide within the first diffusion region and beneath the top surface of the substrate; and forming a second silicide within the third diffusion region and beneath the top surface of the substrate, wherein the second diffusion region includes no silicides formed therewithin.
