MAGNETIC FIELD SENSOR AND METHOD FOR MAKING SAME

摘要

A semiconductor chip (100) for measuring a magnetic field comprises a magnetic sensing element (110) which is mounted on, and connected with, an electronic circuit (120). The electronic circuit is produced in a first technology and/or first material, and the magnetic sensing element is produced in a second technology and/or second material different from the first technology/material. Preferably, a compound semiconductor Hall element is adhesively bonded onto a silicon CMOS chip.
