Vertical hall effect-device

摘要

A vertical Hall effect device is provided and includes a Hall effect layer having a first, second, third, and fourth Hall effect region, which are at least partly decoupled from each other. The Hall effect layer has first and second opposite faces and the vertical Hall effect device has a terminal composition comprising a first, second, third and fourth terminal. A low ohmic connecting composition at the first face connects the terminal composition with contacts of the Hall effect regions so that at each Hall effect region the terminal composition is connected to a same first number of at least two contacts being connected to the respective Hall effect region at the first face. The second and third terminals selectively output an electrical signal responsive to a magnetic field, and the first and fourth terminals selectively output the electrical signal responsive to the magnetic field.

1. A vertical Hall effect device comprising:
a Hall effect layer comprising at least a first Hall effect region, a second Hall effect region, a third Hall effect region and a fourth Hall effect region, which are at least partly decoupled from each other; wherein the Hall effect layer has a first face and a second opposite face; wherein the vertical Hall effect device has a terminal composition comprising a first terminal, a second terminal, a third terminal and a fourth terminal; wherein a low ohmic connecting composition at the first face connects the terminal composition with contacts of the Hall effect regions in such a way that at each Hall effect region the terminal composition is connected to a same first number of at least two contacts being connected to the respective Hall effect region at the first face; wherein the second terminal and the third terminal output an electrical signal responsive to a magnetic field, if an electrical energy is supplied to the first terminal and to the fourth terminal and wherein the first terminal and the fourth terminal output the electrical signal responsive to the magnetic field, if an electric energy is supplied to the second terminal and to the third terminal; and wherein a low ohmic layer composition having one or more layer portions; is arranged closer to the second face than to the first face, wherein the low ohmic layer composition connects each of the at least four Hall effect regions to at least one other of the at least four Hall effect regions.
