Abstract

A method of fabricating a plurality of spaced apart submicron memory cells is disclosed, including the steps of depositing a magnetoresistive system on a substrate formation, depositing and patterning a first layer of material to form sidewalls, and depositing a second, selectively etchable, layer of material on the first layer of material, etching the second layer of material to define spacers on the sidewalls of the first layer of material, etching the magnetoresistive system, using the spacers as a mask, to define a plurality of spaced apart submicron magnetic memory cells, and depositing electrical contacts on the plurality of spaced apart submicron magnetic memory cells.
