Description/Abstract

In this paper, a floating ring edge termination structure using minimally sized lightly doped p-rings is proposed. A novel embodiment of the structure involves placement of shallow p(+)-regions offset from the centre of each of the p-well rings to reduce peak electric field at the surface and to reduce sensitivity to oxide interface charges. The structures have been fabricated using an advanced, 2 kV MOS-bipolar process technology. A close match between the simulated and experimental results validates the proposed structure.
