A method for manufacturing a magnetic field transducing device is provided which includes (a) providing a substrate, (b) subjecting the substrate to a semiconductor device fabricating process in order to obtain a magnetic field transducer, (c) forming an oxide over the magnetic field transducer and (d) covering a magnetic film on the oxide in order to obtain the magnetic field transducing device. The semiconductor device fabricating process also includes (b1) utilizing a mask photolithography etching process to form an annular groove on the substrate, (b2) covering a first insulating layer on the substrate and using a second mask photolithography etching process to form a plurality of diffusing openings on the first insulation layer, (b3) forming extrinsic semiconductor region on the substrate exposed by the plurality of diffusing openings, (b4) forming a second insulation layer on the substrate, (b5) utilizing a third mask photolithography etching process to form a plurality of contacts on the extrinsic semiconductor region, and (b6) forming a conductor on the substrate in order to form a connecting line. The magnetic film is preferably made of Ni and Co.
