Zusammenfassung:According to one embodiment, a method for manufacturing a magnetoresistive memory device includes forming a first layer stack on a substrate. A second layer stack including a first ferromagnet is formed on the first layer stack. A mask including a first portion and an opening is formed above the second layer stack. The second layer stack is etched with an ion beam that travels through the opening. The first layer stack is etched by reactive ion etching through the opening.
