Zusammenfassung:An ESD protection device includes a semiconductor body having an upper surface, a plurality of p-type wells that each extend from the upper surface into the semiconductor body, and a plurality of n-type wells that each extend from the upper surface into the semiconductor body, wherein a total area of electrical insulator disposed between the p-type wells and the adjacent semiconductor body is greater than a total area of electrical insulator disposed between the n-type wells and the adjacent semiconductor body.
