Abstract:
A method for forming a conductive contact body of an integrated circuit device, comprising:forming a plurality of conductive lines including a line-type conductive pattern and a shielding dielectric layer on sides and tops of the conductive pattern, on an integrated circuit substrate; forming a dummy dielectric layer in gaps between the conductive lines; patterning the dummy dielectric layer to produce a dummy opening that selectively exposes some of the gaps between the conductive lines; forming an interdielectric layer pattern in the dummy opening; selectively removing the dummy dielectric layer pattern using the interdielectric layer pattern as an etching mask to form a contact opening; forming a conductive layer in the contact opening and that is electrically connected to the substrate; and etching the conductive layer to separate the conductive layer into conductive contact bodies surrounded by the shielding dielectric layer and the interdielectric layer pattern.
