Abstract
A junction termination with an internal field plate, the field plate structure and the junction termination extension region are folded inside the device to make full use of the thickness of the drift region in the body, thereby reducing the area of the termination and relieving the electric field concentration at the end of the PN junction. The breakdown position is transferred from the surface into the body of the original PN junction, and the withstand voltage of termination can reach to the breakdown voltage of the parallel plane junction. Under such design, a smaller area can be obtained than that of the conventional structure at the same withstand voltage.
