Abstract
In one aspect, a Hall effect device includes an implantation layer; an epitaxial layer located above the implantation layer; a trench filled with a dielectric material and extending from a top surface of the epitaxial layer into the implantation layer and defining an enclosed region; a buried layer the epitaxial layer from the implantation layer within the enclosed region; and a contact pad located on the epitaxial layer. The trench reduces a current from the contact pad from traveling in a lateral direction orthogonal to a vertical direction and enables the current to travel in the vertical direction.
