Nitride structure having gold-free contact and methods for forming such structures |
abstract |
A semiconductor structure having a Group III-N semiconductor layer disposed on a substrate. A multi-layer, electrical contact structure in contact with the Group III-N semiconductor layer includes a gold-free contact layer in contact with the Group III-N semiconductor layer; and a gold-free electrically conductive etch stop layer electrically connected to the gold-free contact layer. An electrically conductive via passes through the substrate to the etch stop layer. The structure includes a plurality of electrode structures, each one providing a corresponding one of a source electrode structure, drain electrode structure and a gate electrode structure. The source electrode structure, drain electrode structure and gate electrode structure include: an electrical contact structure and an electrode contact. The electrode contacts have the same gold-free structure and have co-planar upper surfaces. |
