Abstract:
A method of forming a magnetoresistive memory device assembly, comprising:forming a plurality of memory devices supported by a substrate, individual memory devices of the plurality comprising a non-magnetic composition between a pair of magnetic compositions; the memory devices being spaced from one another; forming an electrically conductive material extending over the memory devices and across spaces between the memory devices; forming a patterned mask over the conductive material; the patterned mask covering some portions of the conductive material and leaving other portions exposed; removing the exposed portions of the conductive material; the conductive material remaining after removal of the exposed portions being a plurality of lines; the lines being in one-to-one correspondence with the memory devices and being spaced from one another; the lines having top surfaces and side surfaces; forming a dielectric material extending across the top and side surfaces of the lines; the dielectric material also extending across spaces between the lines; and forming a magnetic material over the dielectric material; the magnetic material extending across the top and side surfaces of the lines; the magnetic material also extending across spaces between the lines.
