Abstract

The present disclosure provides a method for manufacturing semiconductor structure, including forming an insulation layer, forming a first via trench in the insulation layer, forming a barrier layer in the first via trench, forming a bottom electrode via in the first via trench, forming a magnetic tunneling junction (MTJ) layer above the bottom electrode via, and performing an ion beam etching operation, including patterning the MTJ layer to form an MTJ and removing a portion of the insulation layer from a top surface.
