Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A method for forming a semiconductor device, the method comprising:
forming an active fin on a substrate such that the active fin includes a plurality of semiconductor patterns spaced apart from each other in a first direction perpendicular to a top surface of the substrate;
forming a gate electrode on the active fin such that the gate electrode covers a topmost surface of the active fin and extends between the plurality of semiconductor patterns;
forming an interlayer insulating layer on the gate electrode;
forming a conductive line on the interlayer insulating layer; and
forming a contact plug penetrating the interlayer insulating layer such that the contact plug is connected to the conductive line,
wherein:
the contact plug includes a protrusion protruding upwardly from a top surface of the interlayer insulating layer, and
the protrusion has a width in a second direction parallel to the top surface of the substrate, and a width of a lower region of the protrusion is greater than a width of an upper region of the protrusion.
