Galvano-magnetic effect device

A galvano-magneto effect device comprising:

• a. a substrate;
• b. a galvano-magneto effect element mounted on said substrate comprising a thin semiconductor layer of a magnetism sensing material, said galvano-magneto effect element including a plurality of electrodes extending therefrom;
• c. a plurality of leads coupled to said electrodes;
• and,
• d. a cover plate means, having a high magnetic permeability, covering said semiconductor layer, wherein a portion of each of said plurality of leads is coupled to said galvano-magneto effect element on the surface of said element facing said cover plate means such that said leads are sandwiched between said cover plate means and said galvano-magneto effect element and wherein said cover plate means includes an integral embossed portion extending therefrom into the space between said leads towards said semiconductor layer, the thickness of said embossed portion being less than or equal to the thickness of said leads.
