Abstract:
In at least some embodiments, a semiconductor device comprises a source region is formed within a well. The source region comprises a first dopant type, and the well comprises a second dopant type opposite the first dopant type. A termination region is formed within the well, the termination region being aligned with the source region and having an end adjacent to and spaced apart from an end of the source region. The termination region comprises a semiconducting material having the second dopant type. A preselected concentration value of the dopant in the termination region is greater than a concentration value of the second dopant type in the well.
