Abstract
A semiconductor Hall sensor can reduce measuring error due to an unbalanced voltage by decreasing the unbalanced voltage, and improve resistance to electrostatic by suppressing maximum electric field in the sensor. A cross-shaped pattern of the semiconductor Hall sensor includes cutouts at its concave corners. Among the four concave corners of the cross-shaped pattern, consecutive two or four concave corners are provided with the cutouts. Besides, among the four concave corners of the cross-shaped patterns, the consecutive two or four concave corners have an acute angle at the intersection of the input terminal side pattern and output terminal side pattern. The semiconductor Hall sensor becomes insensitive to defects or unbalance of its pattern, thereby being able to reduce the unbalanced voltage as compared with a conventional cross-shaped pattern of the semiconductor Hall sensor.
