Abstract
In one aspect, a Hall Effect sensing element includes a Hall plate having a thickness less than about 100 nanometers an adhesion layer directly in contact with the Hall plate and having a thickness in a range about 0.1 nanometers to 5 nanometers. In another aspect, a sensor includes a Hall Effect sensing element. The Hall Effect sensing element includes a substrate that includes one of a semiconductor material or an insulator material, an insulation layer in direct contact with the substrate, an adhesion layer having a thickness in a range of about 0.1 nanometers to 5 nanometers and in direct contact with the insulation layer and a Hall plate in direct contact with the adhesion layer and having a thickness less than about 100 nanometers.
