ABSTRACT:
An ESD protection structure has: a first P-type semiconductor region connected to a pad; a first N-type semiconductor region coupled with the first P-type semiconductor region; a second P-type semiconductor region coupled with the first N-type semiconductor region and connected to a ground terminal; a second N-type semiconductor region coupled with the second P-type semiconductor region and connected to a ground terminal; and a trigger circuit configured to draw a trigger current from the first N-type semiconductor region when a surge is applied to the pad. The trigger circuit is connected to the first N-type semiconductor region through a resistive element.
