Abstract
A method of manufacturing a semiconductor device includes providing a wafer, forming a memory device which includes phase change material layer on the wafer, completing a wafer level process of manufacturing the semiconductor device, and performing a thermal treatment process on the wafer to densify the phase change material. To this end, the process temperature of the thermal treatment is higher than the crystallization temperature of the phase change material and lower than the melting point of the phase change material.
