ABSTRACT:
A logic circuit comprising an active-pull-down circuit in which electrodes of an active capacitor are formed of a conductive layer in common with one of contact electrodes of neighboring transistors is disclosed. The area for the capacitor is reduced, so that the element-occupied area is minimum even when the absorbing capability of the active-pull-down circuit is designed to be high for reducing a transient duration of an output signal. Besides, capacitor insulation film is used as a mask during a process, so that the process for fabrication of the integrated circuit is simplified.
