摘要:
A phase change random access memory includes a semiconductor substrate, a switching device pattern formed on the semiconductor substrate, a bottom electrode contact pattern formed on the switching device pattern, a phase change layer pattern formed on the bottom electrode contact pattern, and an insulating layer disposed at a portion of an contact surface between the bottom electrode contact pattern and the phase change layer pattern.
