Abstract
A method for fabricating a cell string includes forming an interlayer dielectric layer, a sacrificial layer, and a semiconductor pattern on a semiconductor substrate, such that the interlayer dielectric layer and the sacrificial layer are formed in a first direction parallel with the semiconductor substrate, and such that the semiconductor pattern is formed in a second direction perpendicular to the semiconductor substrate, forming an opening by patterning the interlayer dielectric layer and the sacrificial layer, filling the opening with a metal, and annealing the semiconductor pattern having the opening filled with the metal.
