Abstract :
We present an isolation structure with multiple rings of deep trenches, which has proven to have an excellent latchup suppression capability. The regions between the trenches are contacted, allowing to increase the blocking voltage of the structure by applying an appropriate bias arrangement. A simple model to predict the optimal bias voltages is derived, and compared to TCAD simulations and measurements.
