Hello Unfortunately we're not there yet because no one of those people who claim they're experienced in process design on this list bothered to mention, that I had forgotten the nitride CMP stop in our process for the STI.
So what ever. It's the best we can do.

ESD performance can't be simulated with spice simulators and is typically measured by special equipment; for example for the human-body model one need to have a high voltage capacitor and a resistor. Spice simulators are not able to handle the snapback curve of an ESD event. For ESD structures the layout is very important; they are high current events and one has to make sure that the current is spread equally over the whole structure. This means that the resistance to each point in the ESD structure should not vary much.
