Both the source- and gate-injection induced impact ionizations are identified with the former leading to premature three-terminal breakdown. A 35% improvement of the breakdown voltage could be achieved in an enhanced back barrier HEMT by implanting fluorine ions under the channel region and effectively block the source injection through the buffer layer.</style></abstract><notes><style face="normal" font="default" size="100%">IEEE International Electron Devices Meeting, San Francisco, CA, DEC 15-17, 2008</style></notes><custom7><style face="normal" font="default" size="100%">000265829300033</style></custom7></record></records></xml>
