Original Abstract Submitted
A semiconductor device comprising: first conductive lines spaced apart from each other; and a conductive structure in contact with upper surfaces of the first conductive lines, wherein the conductive structure includes a lower portion of the conductive structure and an upper portion of the conductive structure, wherein the lower portion of the conductive structure is in contact with the upper surfaces of the first conductive lines, wherein the upper portion of the conductive structure is on the lower portion of the conductive structure, wherein a width of the lower portion of the conductive structure decreases as a distance between the lower portion of the conductive structure and the upper surfaces of the first conductive lines decreases, and wherein a width of the upper portion of the conductive structure increases as a distance between the upper portion of the conductive structures and the upper surfaces of the first conductive lines decreases.
