摘要：
An epitaxial layer is supported on top of a substrate. First and second body regions are formed within the epitaxial layer separated by a predetermined lateral distance. Trigger and source regions are formed within the epitaxial layer. A first source region is transversely adjacent the first body region between first and second trigger regions laterally adjacent the first source region and transversely adjacent the first body region. A second source region is located transversely adjacent the second body region between third and fourth trigger regions laterally adjacent the second source region and transversely adjacent the second body region. A third source region is laterally adjacent the fourth trigger region. The fourth trigger region is between the second and third source regions. An implant region within the fourth trigger region is laterally adjacent the third source region.
