Abstract
An inventive Hall element formed from semiconductor material is disclosed. The inventive Hall element comprises a plurality of interconnected portions formed in a common semiconductor layer. Depending on how the portions are interconnected, the Hall element may detect the sum or difference of magnetic field values. The invention enables the realization of very large Hall elements which can be used in electrical meters to measure a magnetic field produced by an electric current.
Claims6
A Hall element comprising
- a body of semiconductor material divided into at least first and second regions,
- a first row of electrical contacts formed on a surface of said first region,
- a second row of electrical contacts formed on a surface of said second region,
- a plurality of connecting means for connecting each contact of said first row to a corresponding contact of said second row, corresponding contacts in said first and second row being equipotential,
- first and second current contacts formed in contact with said semiconductor body for applying a current to said semiconductor body, said current flowing through said first region, through said connecting means, and through said second region, and
- first and second sensor terminals, said first and second sensor terminals each being connected to an outer one of said connecting means.
