Abstract:
A monolithically integrated inductor, comprising:a layer sequence formed of a plurality of mutually respectively alternating conductive layers and insulating layers disposed such that said conductive layers and said insulating layers are stacked above one another, said insulating layers formed in a whole-area manner, said conductive layers having central regions and edge regions contiguous with said central regions, in which said edge regions in successive ones of said conductive layers are offset relative to one another; additional insulating layers, one of said additional insulating layers disposed in one of said central regions and said edge regions of each of said conductive layers, said additional insulating layers replacing said conductive layers in said central regions and said edge regions; contacts connecting said conductive layers to one another via holes through said insulating layers, said contacts between successive ones of said conductive layers disposed in each case in said insulating layers in regions close to said edge regions; and giant magnetic resistance materials, said layer sequence having a central region with a trench formed therein filled with said giant magnetic resistance materials forming a magnetoresistive random access memory cell, said central region of said layer sequence defined by said central regions of said conductive layers.
