Abstract
Herein disclosed is a semiconductor integrated circuit device comprising a SRAM which is composed of a memory cell having its high resistance load element and power source voltage line connected with the information storage node of a flip-flop circuit through a conductive layer. At the same fabrication step as that of forming the plate electrode layer of a capacity element over the conductive layer formed on the portion of the information storage node through a dielectric film, an electric field shielding film for shielding the field effect of a data line is formed over the high resistance load element through an inter-layer insulation film.
