Abstract
A method for fabricating a semiconductor device includes the steps of forming a magnetic tunneling junction (MTJ) on a substrate, forming a spin orbit torque (SOT) layer on the MTJ, forming an inter-metal dielectric (IMD) layer around the MTJ and the SOT layer, forming a first hard mask on the IMD layer, forming a semiconductor layer on the first hard mask, and then patterning the first hard mask.
