    摘要: A semiconductor memory device and a method of fabricating the same are disclosed. The semiconductor memory device may include a conductive layer doped with impurities, a non-conductive layer on the conductive layer and undoped with impurities, an interlayer insulating film on the non-conductive layer and having a contact hole for exposing an upper surface of the non-conductive layer, an ohmic tungsten film on the contact hole, a lower portion of the ohmic tungsten film permeating the non-conductive layer to come in contact with the conductive layer, a tungsten nitride film on the contact hole on the ohmic tungsten film, and a tungsten film on the tungsten nitride film to fill the contact hole.
