  • Abstract
    Both gate and source/drain electromigration are significant failure mechanisms in power MESFTs. The correlation between electromigration effects due to high current density and measured electrical degradation is investigated in devices of different technologies. A safety zone of operation for ohmic contact electromigration is defined.
