  • HALL EFFECT SENSOR WITH LOW OFFSET AND HIGH LEVEL OF STABILITY
    Publication number: 20240099159
    Abstract: A magnetic field magnetic field sensor and method of making the sensor. The sensor and method of making the sensor may comprise a material or structure that prevents the admission of light in certain wavelengths to enhance the stability of the magnetic field sensor over a period of time. The sensor and method of making the sensor may comprise an adsorption prevention layer which protects the semiconductor portion of the magnetic. The sensor may also comprise an insulating layer formed between semiconductor layers and a substrate layer.
    Type: Application
