Abstract :
We study the SOI poly-defined lateral diode and its optimization to achieve high second breakdown current, low resistance and low capacitance. A second breakdown current of more than 12 mA/mum is achieved. We present a novel failure mechanism for the diode wherein oxide breakdown occurs during a CDM-like event; floating the poly gate is shown to reduce this susceptibility. We also introduce a biasing method for a gated diode that reduces loading capacitance without impacting ESD performance.
