STACKED TYPE MAGNETIC FIELD DETECTION SENSOR

摘要

Disclosed herein is a stacked type magnetic field sensor. The stacked type magnetic field detection sensor includes a vertical hall device including a first substrate of a thickness having a first gate length on which a first circuit pattern in a vertical direction is formed so as to sense magnetic field horizontally input and converting the magnetic field into a voltage signal; and a signal processing circuit unit including a second substrate having a thickness having a second gate length to receive the voltage signal so as to detect a magnitude in the magnetic field according to the magnitude in the voltage and detecting the magnitude in the magnetic field by processing the voltage signal through the plurality of second circuit patterns. By this configuration, magnetic detection sensitivity can be improved, the magnetic field detection sensor can be miniaturized, and IC manufacturing costs can be saved.
