ABSTRACT:
An edge termination structure includes a final dielectric trench containing permanent charge. The final dielectric trench is surrounded by first conductivity type semiconductor material (doped by lateral outdiffusion from the trenches), which in turn is laterally surrounded by second conductivity type semiconductor material.
