发明名称 Nonvolatile memory device and method for fabricating the same
摘要 Provided are a nonvolatile memory device and a method for fabricating the same. The method includes sequentially stacking on a semiconductor substrate a first interlayer dielectric film, a first sacrificial layer, a second interlayer dielectric film, and a second sacrificial layer, forming a resistance variable layer and a first electrode penetrating the first and second interlayer dielectric films and the first and second sacrificial layers, forming an upper trench by removing a top portion of the first electrode, filling the upper trench with a channel layer, exposing a portion of a side surface of the resistance variable layer by removing the second sacrificial layer, forming an insulation layer within the channel layer, and forming a second electrode on the exposed resistance variable layer.

主权项 1. A method for fabricating a nonvolatile memory device, the method comprising: sequentially stacking on a semiconductor substrate a first interlayer dielectric film, a first sacrificial layer, a second interlayer dielectric film, and a second sacrificial layer; forming a resistance variable layer and a first electrode penetrating the first and second interlayer dielectric films and the first and second sacrificial layers; forming an upper trench by removing a top portion of the first electrode; filling the upper trench with a channel layer; exposing a portion of a side surface of the resistance variable layer by removing the second sacrificial layer; forming an insulation layer within the channel layer; and forming a second electrode on the exposed resistance variable layer.
