Abstract

In this disclosure we propose a novel and unique process design architecture directly applicable to smart power integrated circuits, for achieving very high high-side breakdown voltage without enhancing process complexity. The technique is specially suited to smart power platforms where high-voltage devices are integrated with low and medium voltage devices using deep trench based isolation.
