Method of producing an integrated micromagnet sensor assembly |
摘要 |
A method of integrating a permanent bias magnet within a magnetoresistance sensor comprising depositing an alternating pattern of a metal material and a semiconductor material on or within a surface of an insulating substrate; depositing a mask on the surface of the insulating substrate to create an opening above the alternating pattern of metal material and semiconductor material; applying a magnetic paste within the opening above the alternating pattern of metal material and semiconductor material; curing the magnetic paste to form a hardened bias magnet; removing the mask; and magnetizing the hardened bias magnet by applying a strong magnetic field to the hardened bias magnet at a desired orientation. |
