Abstract

A semiconductor device includes a magnetic tunneling junction (MTJ) on a substrate, a top electrode on the MTJ, a trapping layer in the top electrode for trapping hydrogen, a first inter-metal dielectric (IMD) layer on the MTJ, and a first metal interconnection in the first IMD layer and on the top electrode. Preferably, a top surface of the trapping layer is lower than a bottom surface of the first IMD layer.
