Various embodiments of the present disclosure are directed towards methods for forming conductive lines and conductive sockets using mandrels with turns, as well as the resulting conductive lines and sockets. A conductive socket of the present disclosure may have a top layout with at least one turn and with a width that is substantially the same as that of conductive lines along the at least one turn. Such a top layout may reduce loading during formation of the conductive socket. Conductive lines of the present disclosure may comprise outer conductive lines and inner conductive lines having ends laterally offset from ends of the outer conductive lines along lengths of the conductive lines. Formation of the inner and outer conductive lines using a mandrel with a turn may enlarge a process window while cutting ends of a sidewall spacer structure from which the inner and outer conductive lines are formed.
