Abstract
A method for fabricating a semiconductor device includes the steps of first forming a magnetic tunneling junction (MTJ) on a substrate, forming a top electrode on the MTJ, forming an inter-metal dielectric (IMD) layer around the top electrode and the MTJ, forming a landing layer on the IMD layer and the MTJ, and then patterning the landing layer to form a landing pad. Preferably, the landing pad is disposed on the top electrode and the IMD layer adjacent to one side of the top electrode.
