| 摘要 |
A semiconductor device comprises a semiconductor substrate having first and second active regions of first conductivity type, first and second insulated electrodes crossing the first and second active regions, respectively, a third insulated electrode formed on the second insulated electrode, source/drain regions formed on both sides of the first electrode, pseudo source/drain regions formed on both sides of the second electrode, first and second power source lines formed above the second active region through an interlevel insulating layer, a first interconnection connecting the third electrode and the pseudo source/drain regions to the first power source line, and a second interconnection connecting the second electrode to the second power source line, wherein the first active region constitutes a MOS transistor and the second active region constitutes a bypass capacitor and induces an inversion layer of the second conductivity type under the second electrode structure when the power source lines are activated.
