Semiconductor device including dummy

A semiconductor device comprising:

• a lower layer having a plurality of linear active regions and a plurality of linear isolation regions, wherein the plurality of active regions and the plurality of isolation regions each extend longitudinally in a first direction, and the active regions are alternately disposed with the isolation regions across a semiconductor substrate;
• and
• an insulating layer disposed on the lower layer;
• and
• contact plugs each extending through the insulating layer,
• wherein the plurality of active regions include a first active region, and a second active region that is spaced from the first active region in a second direction and comprises a dummy portion and a connecting portion which are electrically insulated from each other and have the same width, and
• wherein the plurality of contact plugs include a first contact plug adjacent the dummy portion of the second active region and electrically connected to the first active region, and a second contact plug electrically connected to the connecting portion of the second active region.
