PROCESS FOR MANUFACTURE OF A GMR BRIDGE SEMSOR AND A GMR BRIDGE SENSOR

摘要

PURPOSE: A Giant Magneto resistive Ratio bridge sensor and the bridge sensor itself which connects magnetoresistive resistors into a bridge to detect a magnetic field is provided to attain low cost process. CONSTITUTION: A process for producing a Giant Magneto resistive Ratio bridge sensor comprises a material which shows Giant Magneto resistive Ratio Effect. The magnetoresistive sensitivity of the individual resistors is caused by tempering. Tempering the resistors is done by selectively directing a current into the bridge connections(5-8) which is sufficient to achieve the temperature required for tempering.
