Claim:
1. A semiconductor device, comprising: a multi-fin active including N sub-fins in a substrate; impurity areas on the sub-fins; and a contact plug on the impurity areas having a smaller horizontal width than the multi-fin active, wherein the N sub-fins include a first sub-fin at the outermost portion of the multi-fin active and a second sub-fin near the first sub-fin, and a straight line perpendicular to a surface of the substrate and passes through a virtual bottom edge of the contact plug is disposed between the first sub-fin and the second sub-fin, or through the second sub-fin, and wherein the virtual bottom edge of the contact plug is defined at a cross point of a correlation line extending on a side surface of the contact plug and a horizontal line in contact with a lowermost end of the contact plug and parallel to the surface of the substrate.
