Manufacturing method of magnetoresistive effect sensor

Image Number 12 for United States Patent #7086141.

A manufacturing method of an MR sensor including a step of stacking an anti-ferromagnetic layer made of an electrically conductive anti-ferromagnetic material, a step of stacking a pinned layer on the anti-ferromagnetic layer, a step of stacking a nonmagnetic spacer layer on the pinned layer, a step of exposing at least once a surface of the nonmagnetic spacer layer to an oxygen-contained atmosphere, a step of stacking a free layer on the nonmagnetic spacer layer, a magnetization direction of the free layer being free depending upon a magnetic filed applied thereto, and a step of providing the pinned layer a magnetization direction fixed by an exchange coupling between the anti-ferromagnetic layer and the pinned layer.
