Abstract

The present disclosure provides a method for manufacturing the semiconductor structure. The method includes forming an Nth metal layer, forming a plurality of magnetic tunneling junctions (MTJs) over the Nth metal layer, the plurality of MTJs having at least one of mixed pitches and mixed sizes, forming a top electrode via concaving upward over each of the plurality of MTJs, and forming an (N+M)th metal layer over the plurality of MTJs. A semiconductor structure manufactured according to present disclosure is also provided.
