Abstract:
1. A Hall sensor element, comprising: a substrate having a main surface; an electrically conductive active region extending from the main surface into the substrate; an electrically conductive first buried layer in the substrate, which contacts the active region at a first lower contact surface; a first upper contact electrode, which contacts the active region at the main surface; wherein the first upper contact electrode is situated diagonally offset to the first lower contact surface so that a first operating current flows between the lower contact surface and the first upper contact electrode diagonally inclined with respect to the main surface, along a first connecting line inclined by 45° with respect to the main surface; a second electrically conductive buried layer, which contacts the active region at a second lower contact surface; and a second upper contact electrode, which contacts the active region at the main surface; wherein the first connecting line between the first lower contact surface and the first upper contact electrode runs inclined to a second connecting line between the second lower contact surface and the second upper contact electrode, and wherein the second connecting line is inclined by 45° with respect to the main surface.
