Stacked magnetoresistance device responsive to a magnetic field generally perpendicular to a side face running along a channel of the device

Abstract

A magnetoresistance device comprises a substrate, an elongate semiconductor channel extending in a first direction and at least two conductive leads providing a set of contacts to the channel. The device may comprise an optional semiconductor shunt in contact with the channel. The optional shunt, channel and set of contacts are stacked relative to the substrate in a second direction which is perpendicular to the first direction and the surface of the substrate. The device has a side face running along the channel. The device is responsive to a magnetic field generally perpendicular to the side face.
