    摘要: Provided are methods of fabricating a semiconductor device including a phase change layer. Methods may include forming a dielectric layer on a substrate, forming an opening in the dielectric layer and depositing, on the substrate having the opening, a phase change layer that contains an element that lowers a process temperature of a thermal treatment process to a temperature that is lower than a melting point of the phase change layer. Methods may include migrating a portion of the phase change layer from outside the opening, into the opening by the thermal treatment process that includes the process temperature that is lower than the melting point of the phase change layer.
