WebA planar multiple floating field-limiting ring structure, designed for above 600V blocking capability, is analyzed in this work. We have proven by simulation and experiment that adding a well designed buffer layer in the epi-substrate region counteracts on the drop in electric field which is due to the space charge limited current and as such the buffer … WebBut so-called OFP-FLR-structures (Offset Field Plate - Field Limiting Rings) are realizable in spite of the restrictions of the used process. For breakdown voltages up to 2000V a lot of field rings are necessary resulting in large and complex structures combined with small sub-elements. In the past amongst analytical met hods, main1 y
