Claim 16:
17. An integrated circuit device, comprising:
a substrate;
a first electrically insulating layer on the substrate;
an electrically conductive contact plug extending at least partially through the first electrically insulating layer, said contact plug comprising 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 having a terminal end, which extends on a first portion of the protrusion; and
a second electrically insulating layer extending on a second portion of the protrusion and on the first electrically insulating layer, said second electrically insulating layer having a sidewall extending opposite a sidewall of the terminal end of the electrically conductive line.
