Abstract
In this article we will report on a high yield HEMT/PM-HEMT technology, based an optimised ohmic contact formation and gate recessing. With this technology active device fabrication yields are better than 90% and corresponding key parameter tollerances always better than ± 5%, as required for high yield MMIC fabrication.
