Abstract
A semiconductor device comprises a piece of semiconductor material. On a surface of said piece of semiconductor material, a number of electrodes exist and are configured to assume different electric potentials. A guard structure comprises a two-dimensional array of conductive patches, at least some of which are left to assume an electric potential under the influence of electric potentials existing at said electrodes.
