Magnetic field sensing element and device having magnetoresistance element and integrated circuit formed on the same substrate |
摘要 |
A magnetic field sensing element comprises an underlayer formed on a substrate, a giant magnetoresistance element formed on the underlayer for detecting a change in a magnetic field, and an integrated circuit formed on the substrate for carrying out predetermined arithmetic processing based on a change in a magnetic field detected by the giant magnetoresistance element, wherein the giant magnetoresistance element and the integrated circuit are formed on the same surface.
