ABSTRACT:
A method for fabricating a three terminal magnetic (TTM) sensor of a magnetic head according to one embodiment includes fabricating a P-type semiconductor material; fabricating an N-type semiconductor material at an upper surface of a portion of said P-type semiconductor material; fabricating a spin valve structure upon said N-type semiconductor material; engaging a collector lead to said P-type semiconductor material; engaging a base lead to said N-type semiconductor material; and engaging an emitter lead to said spin valve structure.
