Nerve impulse signal stimulation device and method for fabricating the same

A method for fabricating a nerve impulse signal stimulation device, comprising:

• providing a substrate having a first surface and a second surface opposite to the first surface;
• forming a first metal layer on the first surface of the substrate;
• forming a second metal layer on the first metal layer;
• forming on the second metal layer a patterned resist layer that covers the second metal layer under the patterned resist layer;
• continuing formation of the second metal layer on a portion of the second metal layer that is not covered by the patterned resist layer;
• removing the patterned resist layer and the first metal layer and the second metal layer that are under the patterned resist layer so as to form a plurality of openings that expose a portion of the first surface of the substrate, a portion of the first metal layer and a portion of the second metal layer;
• and
• attaching a ferromagnetic material to the second surface of the substrate.
