摘要： An integrated circuit device includes a substrate and a first electrically insulating layer on the substrate. An electrically conductive contact plug is provided, which extends at least partially through the first electrically insulating layer. The contact plug includes a protrusion having a top surface that is spaced farther from the substrate relative to a top surface of a portion of the first electrically insulating layer extending adjacent the contact plug. An electrically conductive line is provided with a terminal end, which extends on a first portion of the protrusion. A second electrically insulating layer is provided, which extends on a second portion of the protrusion and on the first electrically insulating layer. The second electrically insulating layer has a sidewall, which extends opposite a sidewall of the terminal end of the electrically conductive line.
