Abstract
Magnetic field sensor having a vertical Hall sensor element arranged in a semiconductor substrate, and an exciting conductor arrangement having at least one exciting conductor, the exciting conductor being arranged within an exciting conductor plane which is spaced apart, in parallel to the substrate surface, from the vertical Hall sensor element at a vertical distance hhaving a tolerance range Δhwhich is due to the manufacturing process, and which exciting conductor further has a lateral distance das an offset from a center position which is located, in relation to the substrate surface, perpendicularly to the vertical Hall sensor element, and the lateral distance dbeing dimensioned such that a vertical calibration component Bof a magnetic flux density Bcreated by the exciting conductor arrangement in the vertical Hall sensor element changes by less than 5% within the tolerance range Δhfor the vertical distance h.
