Abstract
A vertical Hall sensor which is integrated in a semiconductor chip has at least 6 electric contacts which are arranged along a straight line on the surface of the semiconductor chip. The electric contacts are wired according to a predetermined rule, namely such that when the contacts are numbered through continuously and repeatedly with the numerals 1, 2, 3 and 4 starting from one of the two outermost contacts, the contacts to which the same numeral is assigned are electrically connected with each other.
