Abstract
The present disclosure provides a semiconductor structure having a memory region. The semiconductor structure includes an Nth metal layer in a memory region and a periphery region, the periphery region spanning a wider area than the memory region, 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, a top electrode via over each of the plurality of MTJs; and an (N+M)th metal layer over the plurality of MTJs. A method for manufacturing the semiconductor structure is also disclosed.
