We use gate-driven power clamp structure for power pad ESD protection.
As below picture,
before ESD zapping, there is a small overshoot during 0.6V~1.2V;
after ESD zapping, the overshoot is higher, that's to say, there is higher leakage.
But, function test and leakage test at 3V both pass.
Can I say ESD passed?
How can I explain this IV curve?
