Abstract
A method for fabricating semiconductor device includes the steps of: forming a first inter-metal dielectric (IMD) layer on a substrate; forming a magnetic tunneling junction (MTJ) on the first IMD layer; forming a liner on the MTJ and the first IMD layer; removing part of the liner to form a spacer adjacent to the MTJ; and forming a second IMD layer on the first IMD layer.
