Abstract
A semiconductor structure, comprising a substrate and an interconnect layer disposed over a substrate and extending across a memory region and a logic region. The interconnect layer comprises a plurality of tower structures disposed in the interconnect layer within the memory region. Each tower structure comprises at least one metal interconnect structure and a magnetic tunnel junction (MTJ) structure stacked on the metal interconnect structure. The plurality of tower structures are arranged on the substrate in a XY staggered pattern. The at least one metal interconnect structure and the magnetic tunnel junction (MTJ) structure in each tower structure are substantially symmetric along a stacking direction.
