Abstract
A method for fabricating a semiconductor device includes the steps of: forming a magnetic tunneling junction (MTJ) on a substrate; forming a first inter-metal dielectric (IMD) layer around the MTJ; forming a first metal interconnection adjacent to the MTJ; forming a stop layer on the first IMD layer; removing the stop layer to form an opening; and forming a channel layer in the opening to electrically connect the MTJ and the first metal interconnection.
