  • Abstract
    In this paper a new junction topology, the concave junction, and its application in specific junction terminations are presented. We demonstrate, by solving the ionization integrals in the non-punchthrough case, that the breakdown voltage of this type of junction can be higher than that of the infinite plane junction. Based on numerical simulations, we investigate the use of this property to design peripheral terminations for vertical devices with very deep trenches.
