    摘要: A method of fabricating a phase change RAM (PRAM) having a fullerene layer is provided. The method of fabricating the PRAM may include forming a bottom electrode, forming an interlayer dielectric film covering the bottom electrode, and forming a bottom electrode contact hole exposing a portion of the bottom electrode in the interlayer dielectric film, forming a bottom electrode contact plug by filling the bottom electrode contact hole with a plug material, forming a fullerene layer on a region including at least an upper surface of the bottom electrode contact plug and sequentially stacking a phase change layer and an upper electrode on the fullerene layer. The method may further include forming a switching device on a substrate and a bottom electrode connected to the switching device, forming an interlayer dielectric film covering the bottom electrode and forming a bottom electrode contact hole exposing a portion of the bottom electrode in the interlayer dielectric film.
