Abstract
A conductive structure provides a conductive path from a first region in a semiconductor material to a second spaced apart region in the semiconductor material by forming a plurality of trenches between the first and second regions, implanting a dopant into the bottom surfaces of the trenches, and then annealing the wafer to cause the dopant at the bottom surfaces to diffuse and form a continuous conductive path.
