Claim:
A Hall effect element, comprising: a Hall plate comprised of epi material, wherein the Hall plate comprises: a major planar surface comprising an outer perimeter, wherein the outer perimeter comprises: four corner regions, each having two sides tangential to two respective sides of a square outer boundary associated with the Hall plate, each extending along two sides of the square outer boundary by a corner extent; and four indented regions proximate to the four corner regions, wherein each one of the four indented regions deviates inward toward a center of the Hall plate; and a square core region centered with and smaller than the square outer boundary associated with the Hall plate, wherein the square core region is entirely within the major planar surface of the Hall plate, and wherein a portion of each one of the four indented regions is tangential to a respective side of the square core region, wherein each side of the square core region has a length greater than twice the corner extent and less than a length of each side of the square outer boundary.
