Abstract
This invention relates to a semiconductor layer structure. The semiconductor layer structure described includes a substrate and a buffer layer deposited onto the substrate. The semiconductor layer structure is characterized in that a drain voltage threshold lower than the breakdown voltage threshold is determined by isolating ions that are selectively implanted in just one region of the substrate into the substrate, wherein charge can dissipate from the one contact through the buffer layer towards a substrate region without isolating ions, if the one potential deviates from the other at least by the drain voltage threshold, and wherein the substrate region without isolating ions is located underneath the one contact. The semiconductor layer structure described allows dissipation of currents induced by induction in blocking active structures without damaging the active structures.
