Abstract: A termination structure for a superjunction device on which the net charge between P pylons in an Nnull termination region is intentionally unbalanced and is negative. The P pylons in the termination area are further non-uniformly located relative to those in the active area. A field ring which is an extension of the source electrode terminates at a radial mid point of the termination region.
