A method for manufacturing an electronic device including a semiconductor memory may include forming a first carbon electrode material, surface-treating the first carbon electrode material to decrease a surface roughness of the first carbon electrode material, and forming a second carbon electrode material on the treated surface of the first carbon electrode material. The second carbon electrode material may have a thickness that is greater than a thickness of the first carbon electrode material.

Electronic device and method for manufacturing electronic device

A semiconductor device includes: a first electrode including a carbon layer; a second electrode; a variable resistance layer interposed between the first electrode and the second electrode; and a barrier layer interposed between the first electrode and the variable resistance layer, the barrier layer including nitrogen and carbon. A concentration of the nitrogen in the barrier layer is equal to or higher than that of the carbon in the barrier layer.
