Abstract:
A magnetoresistive random access memory (MRAM) is provided in the present invention, including a conductive plug with a protruding portion extending outwardly on one side and a notched portion concaving inwardly on the other side of the upper edge of conductive plug, and a memory cell with a bottom electrode electrically connecting with the conductive plug, a magnetic tunnel junction (MTJ) on the bottom electrode, and a top electrode on the magnetic tunnel junction, wherein the bottom surface of memory cell completely overlaps the top surface of conductive plug.

Claim (Index 8):
A method of manufacturing a magnetoresistive random access memory, comprising:\n providing a substrate; forming a conductive plug in said substrate, wherein said conductive plug has a protruding portion extending outwardly from the upper edge of said conductive plug; forming a bottom electrode material layer, a magnetic tunnel junction material layer and a top electrode material layer on said substrate and said conductive plug; and performing an anisotropic etch process to pattern said bottom electrode material layer, said magnetic tunnel junction material layer and said top electrode material layer, thereby forming a magnetic memory cell on said conductive plug, wherein said anisotropic etch process over etches said conductive plug and said substrate so that depressed regions are formed on said substrate at two sides of said magnetic memory cell.
