Abstract: A magnetic random access memory (MRAM) device includes a magnetic tunnel junction (MTJ) stack formed over a lower wiring level, a hardmask formed on the MTJ stack, and an upper wiring level formed over the hardmask. The upper wiring level includes a slot via bitline formed therein, the slot via bitline in contact with the hardmask and in contact with an etch stop layer partially surrounding sidewalls of the hardmask.
