Abstract
A method for fabricating semiconductor device includes the steps of first providing a substrate having a magnetic tunnel junction (MTJ) region and an edge region, forming an first inter-metal dielectric (IMD) layer on the substrate, and then forming a first MTJ and a second MTJ on the first IMD layer, in which the first MTJ is disposed on the MTJ region while the second MTJ is disposed on the edge region. Next, a second IMD layer is formed on the first MTJ and the second MTJ.
