Abstract
The present invention discloses a layout in a semiconductor device having conductive layers electrically connected to conductive regions via contact holes beneath the conductive layers. Each of the conductive layers has a layout with different widths at opposite longitudinal ends thereof, respectively, thereby being capable of achieving an improvement in the alignment margin between the conductive layer and the contact hole within a given memory cell area. Where the layout is applied to capacitors, it is possible to avoid the formation of inferior storage electrodes over regions where contact holes are formed.
