Abstract:
1. A method for forming a semiconductor device, the method comprising: forming an insulation layer on a substrate, the substrate including a plurality of first regions and a plurality of second regions, at least one of the second region being disposed between adjacent first regions; forming a plurality of first conductive lines on the insulation layer, the first conductive lines being electrically connected to respective first regions through respective first contacts through the insulation layer; forming a plurality of spacers on sidewalls of the plurality of first conductive lines; forming a plurality of contact holes between the adjacent first contacts by removing portions of the insulation layer between the adjacent ones of the plurality of spacers, the contact holes exposing respective second regions; and forming a plurality of second contacts filling respective contact holes and forming a plurality of second conductive lines electrically connected to respective second contacts.
