  • Publication number: 20160118494
    Abstract: A substrate for a metal oxide semiconductor field effect transistor, and a metal oxide semiconductor field effect transistor, are made available. The substrate encompasses: an n-doped epitaxial drift zone, a p?-doped epitaxial first layer disposed on the drift zone, a heavily n-doped second layer disposed on the first layer, and a terminal formed by p+ implantation, the first layer being in electrical contact with the terminal and being disposed laterally between the terminal and a trench, the trench being formed in the drift zone, in the first layer, and in the second layer. The substrate is characterized in that an implantation depth (P) of the p+ implantation is at least as great as a depth of the trench. The deep p+ implantation can separate adjacent trenches in such a way that a field can no longer attack a gate oxide because it is directed around the gate oxide.
