Abstract

A device includes a semiconductor substrate, a bottom conductive line, a bottom electrode, a magnetic tunneling junction (MTJ), and a residue. The bottom conductive line is over the semiconductor substrate. The bottom electrode is over the bottom conductive line. The MTJ is over the bottom electrode. The residue of the MTJ is on the sidewall of the bottom electrode and is spaced apart from the bottom conductive line.
