Abstract: A magnetic field sensing module including a plurality of magnetic flux concentrators and a plurality of sensing elements is provided. Each of the magnetic flux concentrators extends along a first extension direction, and the magnetic flux concentrators are arranged along a second direction. The sensing elements are respectively disposed at a position corresponding to a position between the magnetic flux concentrators and positions corresponding to two sides of the magnetic flux concentrators arranged along the second direction. Sensing directions of the sensing elements are substantially the same. A measurement method and a manufacturing method of a magnetic field sensing module are also provided.

Abstract: A three-dimensional (3D) in-plane magnetic sensor includes a first magnetic sensor, a second magnetic sensor, a third magnetic sensor and a circuit. The first magnetic sensor, second magnetic sensor and third magnetic sensor are installed on a same plane to measure the magnetic field component of first direction, second direction and third direction, where the third direction is perpendicular to the first and second direction. The third magnetic sensor includes a third fixed layer, a third magnetic insulating layer and a third free layer. The magnetoresistance of the third free layer is an intermediate value in the spontaneous magnetization direction, and is varied when interfered by an external magnetic field. In short, the 3D in-plane magnetic sensor is manufactured with semiconductor processing which does not require vertical adhesion, and also bring the benefits of improved production capacity, prolonged product life, reduced manufacturing cost and time.
