  • Patent number: 8558283
    Abstract: A semiconductor device or a memory which includes the same have a line pattern, and a contact plug, the line pattern including a first linear feature to which the contact plug is connected by design, and a second linear feature having a connecting portion and a dummy portion adjacent the location at which the contact plug is electrically connected to the first linear feature. A second contact plug is electrically connected to the connecting portion of the second linear feature of the line pattern. In the case of a misalignment error or the like, the first contact plug may also be electrically connected to the second linear feature of the line pattern but at the dummy portion thereof so as to not create a short circuit in that case. The dummy portion thus allows a sufficiently large process margin to be secured for the contact plug.

  • Publication number: 20100178773
    Abstract: A first material film is formed on a substrate. Linear second material film patterns are formed on the first material film. Spacer patterns are formed on sidewalls of the second material film patterns, and the second material film patterns are removed to expose portions of the first material film between the spacer patterns. The exposed portions of the first material film are removed to form first material film patterns. Third material film patterns are formed in trenches defined by the first material film patterns. Adjacent first portions of the second material film patterns proximate ends of the second material film patterns are separated by a distance less than twice a width of the individual spacer patterns. In some embodiments, the distance separating the adjacent first portions of the second material film patterns is greater than a minimum feature size, and a width of the individual spacer patterns is approximately equal to the minimum feature size.
