Abstract
A fluxgate sensor is integrated in a semiconductor substrate. The fluxgate sensor has two bar type soft magnetic cores, or a rectangular-ring type soft magnetic core to form a closed magnetic path on the semiconductor substrate, with an excitation coil formed of a metal layer either of the united structure winding the two bar-type cores or two longer sides of the rectangular-ring type core altogether and substantially in a number '8' pattern, or of a separated structure winding the two bar type cores or two longer sides of the rectangular-ring type core, respectively, in a number '8' pattern. Also, a pick-up coil is formed on the two bar-type cores or two longer sides of the rectangular-ring type core, either of the united structure winding the two bar-type cores or two longer sides of the rectangular-type core altogether in a solenoid pattern, or of the separated structure winding the two bar type cores or two longer sides of the rectangular-ring type core, respectively, in a solenoid pattern.
