Abstract

A semiconductor device includes a lower structure including a substrate and a cell structure on the substrate and a plurality of interconnection layers, which are stacked on the lower structure in a first direction extending perpendicular to a top surface of the substrate. An uppermost interconnection layer of the plurality of interconnection layers includes uppermost conductive lines. Each of the uppermost conductive lines includes a lower metal compound pattern, a metal pattern, an upper metal compound pattern, and a capping pattern, which are sequentially stacked in the first direction. The lower metal compound pattern, the metal pattern, and the upper metal compound pattern include a same metallic element.
