    摘要: A manufacturing method to form a memory device includes forming a hard mask on a magnetic stack. A first magnetic stack etch is performed to form exposed magnetic layers. A liner is applied to the exposed magnetic layers to form protected magnetic layers. A second magnetic stack etch forms a magnetic random access memory (MRAM) cell, where the liner prevents shunting between the protected magnetic layers.
